FOREWORD

The basic principle of the screw conveyor remains unchanged todayfrom when Archimedes first used an internal type helix to remove waterfrom the hold of a ship. With the technological innovations of the pastcen.tury and a great deal of research in the field, screw (::onveyors havebecome precision pieces of equipment that can move materials eitherhorizontally, on an incline or vertically. They can be used as feeders,distributors, collectors or mixers and can be equipped to either heat orcool while performing the task. With proper covers and gasketing theybecome weatherproof, dust tight and rodent proof. Their compact designallows them to fit easily into restricted areas that would otherwise beunsuitable for most types of bulk material handling equipment. They aresimple to install and support and require very little maintenance. Per foot,they are undoubtedly one of the most economical types of bulk materialhandling equipment available today.

DESIGN DATAEngineering and Layout

The following section contains all relevant information and basicengineering data that is required for specifying and designing theimportant features of most screw conveyor installations andapplications. There will, however, be instances when the informationherein will be insufficient with which to effectuate proper design due touncommon variables that may be present. Continental staff andengineers have considerable knowledge in the design of screwconveyors for special applications and will gladly assist you with soundsuggestions and recommendations for your particular problem.

Conveyor CapacityThe capacity of a screw coveyor is dependant upon three principle

factors, namely conveyor diameter,. trough loading and speed.

By changing one or all of these variables one ultimately varies the

amount of material per hour the conveyor will handle. A small diameter

conveyor will therefore handle the same amountof material per hour as a

large one by either increasing the speed of the small one or by

augmenting the trough loading. It is important to remember however that

when taken to extremes, this can bring about undesireable effects as an

overfull conveyor can become inefficient and one that turns excessively

fast will subject the components to more rapid wear.

When deciding upon trough loading, it should be taken as a general

guide that the less abrasive and more free flowing a material tends to be,

the fuller the trough may be. Conversely, the more abrasive and sluggish

a material is, the less the trough can be filled to allow it to work efficiently.

Therefore, non abrasive, free flowing materials can be conveyed with

trough loadings of 45% while abrasive and sluggish materials require

lower loadings of either 30% or 15%. Exceptions to this rule occur when 8

screw conveyors are used as feeders. This is dealt with further on in the

manual.

Material AnalysisThe initial step in engineering a screw conveyor is to analyse the

material being handled and ascertain its physical properties in order thatthey may be thoroughly evaluated and understood prior to proceedingwith the conveyor sizing and selection. These properties are discussed infurther depth below.

Lump Size: The minimum diameter of a conveyor screw for a givenapplication is determined by the maximum lump size of the materialbeing handled. For this reason, it is necessary to thoroughly analyse thematerial and determine its maximum lump size and the percentage oflumps to total volume along with the minimum particle size and screenanalysis when possible. With this information, proper conveyor sizingcan be effectuated.

Flowability: The flowability of a material greatly affects thehorsepower requirement of the conveyor in question. Flowability isrelated to the angle of repose of a material and therefore, fine free flowingmaterials can be handled at higher trough loadings with lowerhorsepower requirements than coarse, sluggish ones. Please refer to theClassification Code, Table 1 for further information.

Abrasiveness: The more abrasive the material being handled, thegreater the wear the conveyor components are subjected to. For thisreason, it is necessary to determine the abrasive quality of the material inquestion prior to sizing the conveyor. Abrasiveness can be determinedby knowing a material's hardness on a Moh's scale and should this not beavailable the material can be compared with another known abrasivematerial.

Special Applications: These are additional factors which can affectthe operation of the conveyor and are further discussed in the section

entitled Special Applications and Specifications appearing on pages 26and 27 inclusive. '

Moisture Content: Material moisture content is also a factor thataffects material flow. Excessively dry or wet products tend to flow easily,however, many develop sluggish characteristics when having a moisturecontent between the two extremes. This is not accounted for in thematerial tables which follow and such materials should therefore bereclassified.

Duty Cycle: Machinery design also includes selection of the properequipment for the usage it will receive. A conveyor operating for 2 hoursper day does not require the same heavy construction as one designedfor 24 hour usage. This appliesto material thickness and drive sizes alike.Likewise. shock loads to which the equipment and drive are subjected toare an important consideration. Treatment of these factors are notdescribed in suitable enough depth here. however, as previouslymentioned. our engineering staff will gladly assist you to determine thebest conveyor design.

SELECTION PROCEDURE1. Establish Known Factors

The initial step in engineering a screw conveyor is to analyze the

physical characteristics of the material, the rate at which it is to be

handled and the distance over which it is to be conveyed.

Screw conveyor capacity is defined in terms of cubic feet per hour.

This must be determined in terms of the maximum capacity that is to be

handled. This capacity is often stated in terms of tons per hour or pounds

per hour. In order to change this to cubic feet per hour one must divide

pounds per hour by the density in pounds per cubic foot. In some cases

the material density may vary for the product being handled. Thus, when

calculating the capacity of the conveyor, it becomes necessary to

establish the maximum capacity in pounds per hour and divide this by the

minimum density of the material. This will give the required capacity of

the conveyor in cubic feet per hour.

2. Classify Your MaterialMaterials are classified as per the Material Classification Code

appearing in Table 1. It is from this that Material Characteristics, Table 2

is compiled. When classifying a material, first look it up in Table 2. If your

material is not listed, it can classified by comparing it with similar

materials that do appear in Table 2 or by referring to the Material

Classification Code, Table. 1.

Reference to specific materials in Table 2 should not be construed as indicating that all of the materials

3. Determine the Design Capacity

Screw conveyors that employ standard, full pitch flighting have aDesign Capacity equal to their required capacity. Required capacity wasdetermined in Step 1 and is the maximum amount of material per hourtheconveyor in question must handle.

DesIgn Capacity, however, is not equal to required capacity when amodified flighting configuration (such as half pitch) is used. This will

alter the output of the conveyor and therefore, when using a modified

flighting, itis necessary to multiply the required capacity by the CapacityFactors appearing in Table 3 in order to obtain th'e Design Capacity. It is

Design Capacity that is then used to establish the conveyor diameter and

speed.

4. Establish the Diameter and SpeedAfter having determined the material classification and the' Design

Capacity of the conveyor in question, refer to the Capacity Charts, Table4, on Pages 18 and 19. The applicable chart forthe material in question isdetermined by referring to the "Capacity Chart No."column in Table 2,Material Characteristics.

Deterrf1ine the appropriate conveyor diameter by referring to the"cubic feet/hour at maximum A.P.M." column. Once the proper conveyordiameter has been selected, verify Table 5 to insure that the diameterselected is large enough to handle the material size in question. Shouldthe lump size be too great for the diameter selected, proceed to the nextlarger diameter that will handle the material. One should note, however,that this applies only to materials comprised of hard lumps that will notbreak up in the conveyor.

Speed is now determined by dividing the Design Capacity arrived atin Step 2 by the relevant figure in the "Cubic Feet/Hour at 1 A.P.M."column of the Capacity Chart in question.

For example, a9" diameter conveyor as shown in .Capacity Chart 5,

Table 4, will handle 80 cu.ft./hour at 1 A.P.M. Thus, if the conveyor inquestion is to handle 640 cu.ft./hour it must turn 80 A.P.M. (640cu.ft./hr+8 cu.ft./hr. @ 1 A.P.M. = 80 A.P.M.).

6. Establish "D" FactorThe "0" factor is a constant that is applied to a particular Component

Group of a given conveyor and takes into account the power f.equired to

overcome friction in the conveyor intermediate hanger bearings. Todetermine "D"; locate the conveyor diameter and bearing material in the

Friction Factor Chart, Table 7. The figure appearing at the intersection isthe "0" factor that is to be used in the horsepower formula.

TABLE 7 FRICTION FACTORS

7. Establish Required HorsepowerThe formula appearing below gives the horsepower (HoP.) required

at the drive shaft of a standard conveyor. The "F" factor referred to in this

formula is obtained from the "Horsepower Factor" column of Table 2,

Material Characteristics.

H.P. = L (OS + OF)

1 000 000

Where:L ::: Overall conveyor length in feet.0 ::: Friction factor "0", Step 6.

S ::: Speed in A.P.M., Step 4.Q ::: Quantity of material conveyed in Lbs./Hr.

F ::: Horsepower factor "F" (from Table 2)

Conveyor flighting deviating in pitch only requires the samehorsepower as standard flighting. If a modified flighting is used, such asribbon flight, additional power will be required. Thus, the horsepowerdetermined above must be multiplied by the appropriate factor from theModified Flight Factor Chart, Table 8.

8. Establish Motor SizeWith the horsepower determined in the preceding step, determine thenecessary motor from Motor Selection, Table 9 for the horsepower inquestion. This table incorporates factors which compensate for theadditional power required to start a conveyor under full load, overcomeminor choking conditions and power losses brought about by drive

inefficiency.

TABLE 9 MOTOR SELECTION

TABLE 10 TORQUE CAPACITY

22

9. Determine Shaft SizeThe maximum horsepower that may be safely applied to a given

shatt, pipe or coupling bolt size at any given speed is determined byverifying their particular torque rating as shown in Torque Capacity,Table 10 found on page 22. These ratings are based on Schedule 40conveyor pipe, cold rolted shafts and standard grade coupling bolts. Forhorsepower ratings of heavier pipes, high torque shafts or bolts andstainless steel or other materials, please contact our engineering

department.To use Table 10, determine the intersection point between the

conveyor speed ard the motor horsepower and read the shaft size,conveyor pipe and standard screw size along the bottom.

10. Component SelectionThe sizing of major conveyor components is determined by Table 6.

These components have been classified according to the physical

properties of the materials they will be subjected to.

The Component Group selected in Step 5 is used to determine the

physical size of the conveyor components after the diameter, horseposer

and shaft size have been established. To use the table, locate the

component group in question and opposite it find the diameter of the

conveyor screw and coupling shafts as determined in Steps 4 and 9

respectively. Now, one can read off the recommended conveyor screw

part numbers and thicknesses of the trough and cover.

11. ExampleA screw conveyor is required to handle 30 T.P.H. of mine run potash

weighing 70 to 80 Ibs./cu.ft. with 90% of volume under 1" however with

the balance being lumps up to 4'.'. The conveyor will have water spray

nozzles along its entire length for dust suppression and 1 paddle per

pitch to effectively distribute the water throughout the conveyed

material. The overall conveyor length is 40 feet.

From Table 2, it is found that Capacity Chart 8 is recommended for

mine run potash with a recommended trough loading of 15%. The actual

volume of material to be conveyed is now calculated:

60,000 Ibs

70 Ibs./cu.ft.30 T.P.H. X 2000 Ibs/ton = = 857 cu.ft./hr.

With this figure, Design Capacity is calculated by multiplying 857

cu.ft./hr by the Capacity Factor 1.08 found in Table 3 for 1 paddle per

pitch. Thus, the design Capacity is 925 cu.ft./hr.

Aeferring now to Capacity Chart 8, the correct conveyor diameter is

selected by looking down the "Capacity in Cubic feet @ maximumA.P.M." column until the proper size conveyor is found for 925 cu.ft./hr.

This is found to be a 20" diameter unit. Lump size must now be checked

using Table 5 and it is found that the minimum conveyor diameter

required to handle 4" lumps at 10% of the total volume is 16". Thus, the

20" conveyor is satisfactory. Next, one finds that a 20" diameter conveyor

will carry 31 cu.ft./hr. @ 1 A.P.M. from the next column over. Now by

dividing 925 cu.ft./hr. by31 cu.ft.fhr. @ 1 A.P.M. we obtain a conveyorspeed of 30 A.P.M.

23

The Component Group is now established as being 3D from Table 2.Next, by referring to Table 6, we find that hard iron bearings arerecommended for a 3D application. The "0" factor is now establishedfrom Table 7 as being 700 for a 20" diameter conveyor. From Table 2 thehorsepower factor of 2.2 is found as being applicable to mine run potash.

Horsepower can now be calculated using the following data:

LD

40 feet700

S = 30 R.P.M.Q = 60,000 Ibs./hr.F = 2.2 (from Table 2, H.P. Factor)

40 (700 X 30 + 60,000 X 2.2)Thus H.P.

1,000,000

HP. 6.12

This horsepower figure is now multiplied by the Modified FlightFactor taken from Table 8 for 1 paddle per pitch. Thus 6.12 X 1.29 = 7.89

H.P. Using 7.89 H.P., we verify Table 9 and select a 10 H.P. motor for the

requirement.Torque capacity is now verified using Table 10and it is found that a

3-7/16" diameter shaft is required to transmit the motor H.P.. From theComponent Selection Shart, Table 6 we find that for a 3D ComponentGroup using a 20" diameter conveyor screw with 3-7/16" shafts, a 20S724unit is required witha 1/4" thick trough and 12 ga. covers.

BEARING RECOMMENDATIONSThe selection of a bearing material for use in intermediate hangers is

one that is based largely on experience coupled with consideration forthe particular characteristics of the material in question. The principalfactor affecting bearing performance between various bearing materialsis a rating factor known as PV (pressure velocity). This rating is amathematical expression of PIA (pounds per inch of projected area) ofload times SFM (surface feet per minute). Thus, the PV value is themaximum load and speed that a bearing may be subjected to.

The following list deals individually with the most popular types ofscrew conveyor bearing materials indicating their particular areas ofstrength and their restrictions. While this list covers most applications, itis far from being complete as to the number of bearing material on themarket today. Should special applications or conditions be encountered,Continental engineers will gladly assist in the selection of a suitable

material.

Babbitt and Bronze BearingsBabbitt and bronze bearings have traditionally been used in

applications where mildy abrasive, irregular or lumpy materials areencountered. Because of their need for oil or grease lubrication, they areunaccpetable in applications where contamination is a deciding factor.Babbitt bearings have a temperature limitation of 130°F while lubricatedbronze are limited to 220°F. The temperature limit for bronze can beextended by using special high temperature alloys and/or syntheticlubricants. The maximum PV of babbitt is approximately 30,000 with amaximum P of 1500 and V of 1200. Bronze on the other hand has amaximum PV of 75,000 with maximum P of 3,500 and V of 750.

24

Self Lubricated BearingsSelf lubricated bearings such as oil impregnated hard maple,

graphited bronze, commercial carbon, sintered bronze andthermoplastic or reinforced fibre have become very popular forapplications involving mild to moderate abrasiveness with irregular orlumpy materials. .

Oil impregnated wood has proven to be an extremely good bearingmaterial. Its major drawback is its inability to withstand highly abrasivecond.itions such as encountered when moving aggregates or sand. Theirtemperature limit is approximately 180°F. In mildly abrasive conditions,wood has the property of embedability which permits grit to becomeembedded in the bearing sidewall then film over with lubricant thusholding the shaft harmless. Its maximum PV is 15,000 with a maximum Pof 2,000 and V of 2,000. Its total PV approaches that of babbitt and cancarry higher speeds or loads individually.

Thermoplastic bearings such as ultra high molecular weightpolyethylene (UHMWP) and nylon are the most regularly encounteredthermoplastics. Both operate effective1y in damp conditions, however,UHMWP is best suited to wet aplications such as ice or fish offalconveyors because of its low rate of water absorption thus minimizingshaft seizure due to bearing swelling. Nylon on the other hand absorbswater at a much higher rate which can lead to swelling problems.Temperature limitations of UHMWP are 180°F while nylon is 250°F.Abrasion resistar:lce of UHMWP is outstanding providing PV limitationsare not exceeded. This same material IS used as chute liners in the gravelindustry. The maximum PV of UHMWP is 4,000 with a maximum P of1,200 and V of 50. Nylon on the other hand has a maximum PV of 3,000with a maximum P of 400 and V of 350.

Graphited bronze bearings are useful in certain applications andhave a maximum PV of 50,000 with a maximum P of 1,500 and V of 1,200.Their maximum operating temperature is 500°F. For higher temperatureapplications, commercial carbon bearings can be used as theirtemperature limits are approximately 600°F.

Hard Iron BearingsHard iron bearings cast in chilled white iron or Ni-Hard@ materia) are

used when handling excessively abrasive materials. They must be usedin conjunction with hardened coupling shafts, which, depending on thecircumstances can be achieved through induction hardening or hardsurfacing the shaft in question. Hard iron bearings are not normallylubricated and have a maximum operating temperature of 500°F. Themaximum PV of hard iron is 75,000 with a maximum P of 8,000 and a V of35.

Because of the absence of lubricant when using hard iron bearingswith hardened coupling shafts, it is necessary to limit the operatingspeed using the formula below in order that wear may be kept to aminimum and that excessive squealing noise caused by dry metal onmetal be eleminated.

Extreme TemperaturesWhen handling materials of extreme temperature, it is necessary to

construct the conveyor with special components and alloys designed tomeet these conditions. (With the use of a jacketed type trough, it ispossible to either heat or cool the material while conveying and keep itwithin a safe operating temperature). Please consult our engineeringdepartment for their recommendations.

Fluidizing MaterialsWhen handling materials which tend to aerate easily and decrease in

density, thereby increasing in volume, it is important to take into accountthe areated density in order that the conveyor size, speed andhorsepower can be adjusted in consequence.

Hygroscopic MaterialsHygroscopic materials which readily absorb moisture must be

handled in tightly sealed conveyors that exclude the exterior

26

The component selection procedure previously outlined takes intoaccount the material's physical characteristics, provides for proper crosssectional loading of the conveyor and specifies, through the componenttables, the type of components best suited for the application in question.Some material characteristics however will require additional specialfeatures. The following should be taken into consideration whenencountered.

Abrasive MaterialsAbrasive materials have a tendency of causing excessive and

accelerated wear on screw conveyor components and should be carriedat low cross sectional loads and slow conveyor speeds. For excessivelyabrasive materials or conveyors subjected to heavy, continuous service,heavy duty components should be specified and abrasive resistant, hardsurfaced materials or alloys should be considered for the application.

Contaminable MaterialsEasily contaminable materials such as foodstuffs and certain

chemicals require special components and construction not necessarilyfound in standard conveyors as outlined in the selection process. Suchspecial components and features often include non lubricatedintermediate hanger bearings, end bearing seals, tightly sealed covers,and often drop bottom troughs for easy access and cleaning of theconveyor. Certain applications may also require continuously weldedflighting on one or both sides of the pipe and special finishes on the weldsto minimize roughness and alleviate contamination. Many materials willalso require stainless steel to eliminate corrosion.

Corrosive MaterialsWhen corrosive materials are encountered it is advisable to use

components manufactured of stainless steel, aluminum or otherresistant alloys. Hot dip galvanizing may be used in non abrasive

applications.

Degradable MaterialsMaterials which have a tendency to break up or separate easily,

thereby affecting quality, should be handled in larger diameter, slowerturning screw conveyors to reduce material agitation.

atmosphere. The fact that the material will also increase in density andbecome more sluggish when in contact with moisture must also be takeninto account when determining conveyor size. horsepower and speed.

Materials that tend to PackMaterials that tend to pack and have a strong resistance to digging

may be handled by a standard conveyor providing they are aerated prior

to being introduced into the conveyor. Some materials which tend to

pack under pressure and become hard in the clearance between the

trough and conveyor screw can be conveyed satisfactorily if the screw

conveyor operates at a slow speed and a cutting edge is applied to the

leading edge of the flight.

Mixing MaterialsIf mixing or aeration of one or more materials is necessary during the

conveying process, ribbon flights, cut flights, cut and folded flights or

anyone of the above in combination with paddles may be employed.

Toxic MaterialsToxic materials that can release harmful dust orvapours during the

conveying stage should be handled in a system of sealed construction. In

some cases an exhaust system may be advisable to remove the toxic

vapour or dust.

Viscous or Sticky MaterialsViscous or sticky materials should be handled by a ribbon type

conveyor screw due to their tendancy to adhere to the flight and pipe

junction point on a standard conveyor. Special coatings applied to the

ribbon can often assist the flow of such a material.

COMPONENT SELECTION AND LAYOUT DATATABLE 11 HAND OF CONVEYOR

When selecting comp0nents for your screw conveyor, please refer toTypical Conveyor Layout, Table 12, and the accompanying diagram forthe dimensional standards and recommended layout arrangements.

Conveyor ScrewsConveyor screws are available as either right or left hand units. Right

hand will be supplied unless otherwise specified. In order to determinethe "hand" of a conveyor, refer to Hand of Conveyor, Table 11. Usestandard length conveyor screws whenever possible. The carrying faceof the screw, which moves the material being conveyed is free of lugs forunimpeded flow. Lugs are positioned on the back or non carrying side ofthe screw at each end to guard against the flight folding back. It istherefore essential that a screw designed for right hand operation beused that way and vice versa for left hand. Bi-directional conveyor screwscan be furnished for specific operations. Flighting should be omittedover the last discharge opening and flight ends at hanger positionsshould be set opposite each other for continuous flow of material acrossthe hanger space.

Note that if the edge of the flight on the near side of the conveyorscrew slopes down to the right, the screw is right hand and if it slopesdownward to the left, the conveyor screw is left hand.

HangersHangers are used as intermediate supports between sections of

conveyor screw. They maintain alignment of the conveyor screws and

provide a bearing support for the coupling shaft.

Hangers must be placed clear of inlet openings. They can be placedat trough joints as they are designed with spacer bars wide enough for

this purpose. Hangers may be fitted with a wide variety of bearing

materials to suit a diverse range of screw conveyor applications.

Couplings and ShaftsCoupling, drive and end shafts connect and transmit power to the

conveyor screws. It is imperative that the shafts selected be of sufficientstrength to handle the horsepower and load Imposed on them. Theirhorsepower rating may be verified as shown in Torque Capacity, Table10, Page 22.

Most conveyor systems are made up of standard components and inorder to replace or renew an intermediate section of conveyor it isnecessary to dismantle the conveyor from one end. The time involved toeffectuate this work can be greatly reduced by using Quick Release Keyson the conveyor screws as shown on page 41. These enable an entiresection of screw to be removed from the center of the conveyor withoutdisturbing preceding sections.

Trough EndsTrough ends support the conveyor screw and the trough. They

incorporate a bearing assembly to maintain clearance between the

28

TABLE 12 TYPICAL CONVEYOR LAYOUT

trough and conveyor screws, and, depending on the direction of materialtravel, incorporate a thrust bearing to maintain clearance between theconveyor screws, hangers and trough ends. This provides for smootheroperation, lower power requirements and less wear on the hangers,bearings and other vital components. The standard duty Type E or theheavy duty Type H thrust bearings will absorb thrust in either direction,however it is preferable that the thrust bearing be positioned at thedischarge end of the conveyor.

Seals are incorporated into the trough ends to prevent leakage intoor out of the trough. They also provide added protection for the endbearings and shafts from the material being handled.

Shelf type trough ends are very often used when handling hotmaterials in order that the bearing and drive can be separated by somedistance from the hot trough. They are also used when handling fine orvery abrasive materials which require more effective sealing than can beachieved with standard seal plates under flange bearings. The sealsgenerally used in these cases are the Split Gland or the Packed Glandtypes ( see page 69 ). When extreme shaft concentricity is required adouble pedestal shelf type trough end is used. This minimizes shaftmounted reducer wobbling.

Troughs and CoversNumerous trough and cover configurations are available for varying

applications. Standard lengths should be used whenever possible. Seethe section on troughs and covers for specific applications of each.Gasketing is available between the trough and cover depending on the

application.

MATERIAL INPUT AND DISCHARGE

Screw FeedersScrew Feeders consist of a specially designed conveyor screw

enclosed within a tubular housing or a trough with a shroud cover. Theyare used for the removal of material at a predetermined rate from astorage medium regardless of the existing head of material. For furtherinformation on these units see the section entitled SCREW FEEDERS onpage 31 of this manual.

[~;I~~~~~~~~~~29

Care should be exercised in controlling the loading of a conveyorsince it is designed to handle a specific maximum volume of material.Difficulties arise when the conveyor is fed from a storage mediumwithout the use of input volume controls. If the rate of material flow is notinherently self regulating or cannot be regulated by other controls, aScrew Feeder or another flow control should be incorporated into thesystem in order that a smooth and constant flow will be delivered to thesystem. By doing so, all surge loads are avoided. Flow regulation byScrew Feeder and Rotary Feeder are discussed in further depth below.

Rotary FeedersRotary feeders employ a cylindrical rotor with pockets of specific

volume which deliver a constant flow of material. Their output capacity isregul.ated by the speed of rotation of the rotor. These units mayfrequently be driven from the conveyor drive or end shaft without thenecessity of an additional drive for the feeder itself.

Multiple InletsInstallations frequently require the use of conveyors with multiple

inlets for feeding from several different sources either individually orsimultaneously. When only one inlet will be open at any given time, a gateor cut off device may be restricted to a maximum opening that will notallow overloading of the conveyor. When more than one gate will beopen, considerable care must be taken to limit the flow from each so thatthe aggregate rate is not in excess of the conveyor design limit.

~."t""-- (~: " ~.!~",. ';;(O""'",-\~,. .~"~

~ -, 1: .

Dead Loads

Screw conveyors loaded directly from a storage medium above theconveyor with a free flowing material are subject to varying dead loadsdue to the hydrostatic head of material and the associated loads createdwhen moving the material from under itself.

This problem can be circumvented by using a side type inletincorporating a slide gate if necessary to relieve the screw from excessivematerial pressures. Screw rotation should always be towards theopening to en~ure a constant flow rate.

30

Impact LoadsFrequent requirements are such that materials must fall vertically to

the conveyor inlet creating the possibility of impact damge to the conveyorscrew due to the inertia of the material particles or lumps. This condition maybe overcome by using deflector plates or cushion chambers in the inlet

spout.

Discharge Spouts

Most discharge spouts are of standard design as shown on page 78 ofthis manual, however special units can be built to adapt to specificmachinery and can be supplied flared or longer than standard. In all cases,flighting is usually eliminated beyound the midpoint of the last dischargeopening on a conveyor in order to effect complete discharge of the materialand alleviate any possibility of material carry-over. When conveyingmaterials that are fluid or easily aerated it may be advisable to install longerthan standard discharge spouts. Intermediate discharge spouts may befitted with a variety of control gates or slides. These slides are often manuallyoperated however they can also be actuated by rack and pinion assemblies,hydraulic or pneumatic cylinders or by special electric gear motorscomplete with limit switches. ~t is advisable that the last discharge spout onconveyors with multiple discharges or the discharge spout of units with asingle discharge be furnished without a slide of any kind on prevent possibledamage to the conveyor in the event of operation with the slide closed.

SCREW FEEDERS

A screw feeder differs from a screw conveyor in that it is designed toregulate the volumetric rate of material flow from a hopper, bin or storageunit. The inlet is flooded to 100% load capacity and by incorporating changesto the flighting (diameter, pitch, etc.) and the speed of the feeder screw, it ispossible to govern the rate of material discharge. The style of flighting usedin a screw feeder is dependent upon the characteristics of the material beingtransported and either a regular pitch, modified pitch or a modified diameterflight is used.

Screw feeders are usually equipped with a shroud cover for a shortdistance beyond the inlet opening. This helps prevent flooding of theconveyor with material. When very free flowing materials are being handledit is often necessary to use extended shroud covers, tubular housings orshort pitch flighting for positive material control.

I{!:I continantal,131

Uniform Diameter and Pitch Feeders

This type of screw feeder is generally used for handling fine, freeflowing materials. Because the regular diameter and p.itch brings aboutmaterial flow from the forepart of the inlet and not along its entire length,this type of unit should only be used when a hopper is to be completelyemptied or where inert or dead areas of material overthe ir)letdo not posea problem. Should the material being handled be on an extremely fine orfree flowing nature, a shortened or half pitch flight should be used toprevent flooding and overloading of the conveyor being fed.

Variable Pitch Feeders

Screw feeders having a variable pitch are generally used inconjunction with a screw conveyor in which the material is choke fedfrom a bin or hopper. The short pitch handles the full cross sectional loadand .as tt,e mat~rial is tran~ferred int<? the long~r pitch s~ction, the. crosssectional load IS reduced In proportion to the Increase In screw pitch.

This type of unit is best used with standard or relatively short inlets.When the inlet runs the entire length of a hopper or bin, it is preferable toutilize a tapered diameter screw feeder.

Tapered Diameter Feeders

Screw feeders having tapered flights are generally used to conveymaterials containing a considerable percentage of lumps They are alsoextensively used when it is desirable to draw material from a bin orhopper along its entire length thereby eliminating dead or inert materialIn the forepart of the opening. Using a tapered flight feeder instead of aregular flight will, in most cases, especially when the feed or inletopenings is 10ng...f6onsume much less horsepower.

32

Multiple Diameter Feeders

This isa combination feeder and conveyor, the phystcal dimensionsbeing variable on each. The small diameter feed end operates at fullcross sectional loads and, upon reaching the larger diameter, reduces toa safer level in proportion to the change in diameter.

These units are generally employed when it is undesirable to use avariable pitch section under an inlet be it due to the need to eliminatedead areas, because of an excessively long inlet from a bin or hopper orbecause the lump size of the material in question is not compatible withthe short portion of the variable pitch. It is worthwhile to note here thatthe feeder portion of a multiple diameter screw can be tapered should itbe desirable.

Live Bottom Feeders

Live bottom feeders are used to discharge materials from straightsided bins and are composed of several horizontal screws side by sidewhich cover the complete area of the bin bottom. The material istherefore drawn out equally from the full width into a collecting conveyorthat runs at right anglesto the bin bottom screws. The live bottom feederis used to discharge materials that have tendency to pack and bridgeeasily under pressure.

Screw Feeder Capacity

Table 4, Capacity Chart 9 appearing on Page 19, gives the capacities

of standard screw feeders having fixed diameters and standard pitch

flighting. These units, employing standard conveyor screws, will handle

most Class A and B materials. In order to adapt them to handle materials

not covered by these classes or for special feeding applications where

inlets are extended or material volume above the feeder is excessive, it

becomes necessary to use a combination of one or all of the modifica-

tions to the flight as previously discussed in this section.

Due to the complexity of screw feeder design, we recommended that

you consult our Engineering Department for proper recommendations

concerning your particular needs.

INCLINED S~:REW CONVEYORS

Screw conveyors may be used in the inclined plane and when spaceallows, this can be a very economical method of both elevating andconveying simultaneously. It is most important however to understandthat as the angle of inclination increases, the capacity of the given unitrapidly decreases. The critical angle at which it becomes most difficulttoconvey material on an incline is 450. As one approches this anglecapacity drops very dramatically and once past this critical point and ontowards 900, the efficiency of the unit increases again.

Numerous methods of conveying on an incline are used amongwhich are shorter than standard pitch, tubular housings or extendedshroud covers. It is also necessary as the angle of inclination becomesgreater to increase the conveyor speed in order to overcome thetendency of the material to fall back upon itself.

Inclined conveyors can rarely be used as feeders for accuratelymeasuring material flow. If an accurate flow rate is necessary, a separatehorizontal feeder conveyor is required.

Since additional power is required to convey material on an inclineand this power is a function of material density, consistency and verticallift, we suggest that our Engineering Department be contacted for

specific recommendations as to the requirements of your particularapplication.

I<!:I continant~~35

VERTICAL SCREW CONVEYORS

The vertical screw conveyor is an extremely efficient and effectivemethod of elevating and distributing bulk materials. As a ruleofthumb, ifa material can be handled by a horizontal screw conveyor, it can also behandled in the vertical plane. By having fewer moving parts, the verticalscrew conveyor does away with many of the difficulties commonlyencountered with other types of elevating equipment.

Amongst the numerous advanteges of this type of unit is its flexibilityof design and arrangement. One can convey up to 6000 cu.ft. per hourusing a 16" diameter unit to a height of about 75 feet depending onmaterial weight and the drive arrangement. These units are space savingand transfer material from the horizontal to the vertic:al plane veryefficiently. Positive discharge is achieved in any direction and little or nomaterial segregation or degradation occurs throughout the process.Since judgement and experience in conveying are required we againsuggest you contact our Engineering Department for our specificrecom mendations.

DRIVE ASSEI\1BLIES AND ARRANGEMENT

Numerous combinations and types of drives are available for screwconveyors. Some of the more frequently used drives and mechanicalarrangements are described below.

Such a unit isusually used where special sealingarrangements are required on theconveyor shafts, such as a packedgland seal, or where very high hor-sepower must be transmitted whichis not within the parameters of thescrew conveyor drive.

Other Drives and ConfigurationsNumerous other methods of driving a screw conveyor are available

among which are variable speed D.C. motors with SCR rectifiers,hydraulic drives or variable pitch sheaves between motor and reducer.Also, when inertia loads are encountered when starting heavily loadedconveyors or when high horsepowers are used on large or longconveyors, fluid couplings should be incorporated in the drivearrangement. We suggest you contact our Engineering Department forspecific suggestions and recommendations regarding such matters.

SPECIAL FABRICATION MATERIALS

Screw conveyors are normally fabricated of low carbon, hot rolledsteel plate with the exception of the drive, end and coupling shafts whichare of cold rolled bar stock. Certain materials and conditions howeverrequire the use of materials other than mild steel. These materials andtheir advantages are discussed in further depth in the followingparagraphs. Further information and assistance can be obtained fromour Engineering Department for your particular applications.

Hard Surfaced Conveyor Screws

Conveyor screws that will be in contact with highly abrasivematerials are often hard surfaced using fusible alloy hard surfacingmaterials or hard facing electrodes. These materials are applied to theflight surface in a width proportional to the conveyor's cross sectionalload. These dimensions are given in Table 13. The dimensions givenpertain to standard application however for extremely abrasiveconditions or higher than normal trough loadings, it may be advisable toharden the full flight face, periphery and even the pipe.

Abrasion Resistant Steel

If necessary, conveyor screws and components can be supplied

fabricated of abrasion resistant metals with a surface hardness of up to

360 Brinell. This can substantially increase the life of components

such as conveyor screws and troughs which are subjected to the greatest

wear and therefore substantially increase their useful life.

Stainless Steel and Other Alloys

Many requirements call for the use of materials other than mild steel

to be in contact with the conveyed material due to uncommon variables

such as corrosion, contamination or elevated temperature. To suit these

conditions fabrication materials such as stainless steel, Monel, Inconel

and aluminum alloys may be used to suit the applications.

Coating and Plating

Conveyor screws and components may also be plated or dipped to

suit numerous requirements and conditions. Hot dip galvanizing, nickle

or chrome plating and rubber or Teflon coating are often encountered.

High Torque Drive Components

Certain applications may arise where the normal horsepower range

of standard screw conveyor components will be exceeded. For cases

such as these high capacity coupling bolts, shafts and pipes are

available.

0-- Helicoid DesignationThe letter 'H' indicates screw conveyor with helicoid flighting. The figures

to the left of the letter indicate the nominal outside diameter of the conveyor ininches. The first figure following the letter is twice the diameter of the cou-plings in inches. The last two figures indicate the nominal thickness of flightingat the outer edge in 1/64". Thus 12H408 indicates a 12" diameter helicoidconveyor for 2" couplings with flighting 8/64" or 1/8" thickness at outer edge.

Due to the nature of the forming process, the periphery of a helicoid flight isapproximately 1/2 the thickness of the material at the root where it is welded tothe pipe. Because most wear is concentrated on the periphery, helicoid flightsare less suitable for handling abrasive materials than sectional flights.

Sectional Designation:The letter'S' indicates screw conveyor with sectional butt welded flighting.

The figures to the left of the letter indicate the nominal outside diameter of the

conveyor in inches. The first figure following the letter is twice the diameter of

the couplings in inches. The last two figures indicate the nominal thickness of

flighting in 1/,64/'. Thus 12S612 indicates a 12// diameter sectional conveyor for

3" couplings with flighting 12/64" or 3/16'/ nominal thickness.

Sectional flights, due to the nature of the forming process, maintain a uniform

thickness between the root and the periphery. They are thus more suitable for

abrasive applications due to the greater thickness of material at the point

subjected to the greatest wear.

CONVEYOR SCREWS

Helicoid Conveyor Screws:Helicoid flighting is formed by cold rolling special analysis strip into a continuous

helix that produces a work hardened, smoothly finished flight surface. The flighting isthen fastened to the pipe by intermittent welds with steel end lugs at each extremity toreinforce the tips. They may also be continuously welded on either one or both sides ifso required. The pipe has seamless internal collars inserted and plug welded in bothends to accept the shafts. Both helicoid and sectional flighting of the same diameter andshaft size are interchangeable.

Sectional Conveyor Screws:Sectional flights are blanked from a steel plate, formed into a helix and then butt

welded together to form a continuous helix on the pipe. The flights are normally fastened

to the pipe by intermittent welds however can be continuously welded on one or both

sides if required. The pipe has seamless internal collars inserted and plug welded in both

ends to accept the shafts. Sectional flight conveyor screws can be supplied in special

diameters, pitches, thicknesses, pipe sizes and shaft diameters as well as in a variety of

materials such as stainless steel, Inconel, Monel, copper, brass and other metals.

Sectional Flights:Sectional flights are formed from steel plate with a lead slightly longer than their

pitch. This assures a tight grip when mounting them on the pipe. They are available in allstandard sizes and can also be supplied in special diameters, pitches, thicknesses andpipe sizes.

Ribbon Flights:Ribbon flights are commonly used to handle sticky or gummy materials which

normally build up at the pipe of flight junction point. Their open design minimizes thisproblem. They are also used for mixing dry materials in transit as long as the crosssectional load is greater than the face of the flight. The pipe has seamless internal col-lars inserted and plug welded in both ends to accept the shafts. Ribbon flight can besupplied in special diameters. pitches, thicknesses, pipe sizes and shaft diameters aswell as in a variety of materials such as stainless steel, Inconel and Monel.

Paddle Conveyor Screws:Paddle conveyor screws are commonly used to mix material in transit when con-

veying efficiency is not important. The paddles are bolted through the pipe and areinfinitely adjustable. The pipe has seamless internal collars inserted and plug welded inboth ends to accept the shafts. Paddle screws can be supplied in special diameters,pitches, thicknesses, pipe sizes and shaft diameters as well as in a variety of materialssuch as stainless steel, Inconel and Monel.

Cut and Cut & Folded Flights:Notches cut in the periphery of a conveyor screw creates a very effective mixing

action with most materials, particularly at high speeds. By folding over the cut, a moreviolent mixing action is achieved since the material is spilled over itself. The cut flight isalso useful for moving materials which tend to pack while cut and folded flights areuseful in cooling, heating or aerating light substances.

Internal Collars, Coupling Bolts and Quick Release Keys:Internal collars are used in all types of conveyor screws to create a close fit be-

tween the inside diameter of the pipe and the outside diameter of the shaft. Whenpurchased separately they are not drilled for the coupling bolts as the pipe ends arealways drilled after assembly.

Coupling bolts are machined from analysis steel with the thread cut to the properlength so as only the bolt shank is in contact with the coupling shaft and pipe, therebyensuring full torque capacity and minimum wear. Special self-locking nuts are providedto prevent the nut from working loose during operation which can lead to damage anddowntime.

Quick release keys allow for the removal of an intermediate section of conveyorwithout dismantling the entire screw conveyor. To remove a section, the intermediatebolts are removed, the key is removed and the entire section simply lifts out while theshafts remains in position in the trough.

CONVEYOR SCREW SHAFTS

Drive Shafts:

Screw conveyor drive shafts transmit the rotary motion fromthe drive unit to the conveyor screw. They are manufactured ofhigh quality, cold drawn steel to close tolerances for the properbearing clearances. Coupling bolt holes are jig drilled for perfectalignment and key seats are precision milled to insure properassembly. For applications requiring higher torque capacities,they can be supplied in high carbon steel. They are also availablein stainless steel. Contact our Engineering Department for furtherinformation.

End Shafts:

End shafts are designed to provide support of the final screwsection. They are manufactured of high quality, cold drawn steelto close tolerances for proper bearing clearances. Coupling boltholes are jig drilled for perfect alignment. They are also availablein stainless steel.

Coupling Shafts:

Coupling shafts are designed to transmit rotation betweenindividual conveyor screw sections and to provide intermediateradial support through hanger bearings. They are manufacturedof high quality cold drawn steel and have jig drilled bolt holes forperfect alignment. They are available in standard configurationfor use with intermediate hangers and in close coupled configura-tion where the omission of hanger bearings is desireable. For usewith hard iron bearings they are induction hardened to increasetheir wearing capacity. For applications requiring higher torquecapacities they can be supplied in high carbon steel. They canalso be supplied in stainless steel. Contact our EngineeringDepartment for further information.

HANGERS

Style 226:

The Style 226 hanger is the most commonly used in screw c:onveyor appli-cations. Its narrow size and low profile maintains rigidity without compromisingthe material flow. It is designed to mount flush with the trough flarlges and there-fore will not obstruct the trough cover which makes its use desireable with dustand weather tight covers.

Style 220:The Style 220 hanger is identical to Style 226 with the exception that it is

designed for mounting directly to the top of the trough flanges. If it is to be usedin conjunction with trough covers, the cover joints must coincide Y/ith the hanger

positions.

Style 270:

The Style 270 hanger is furnished with a self aligning, sealed ball bearing.This feature reduces friction and thus lowers horsepower requirements makingsuch units desireable for long conveyors or those operating at high speeds.Due to the nature of the ball bearing seal they are not recommended for use in"dirty", gritty or abrasive conditions. An Alemite grease fitting can be suppliedin the event that regreasing is desired.

Style 326:The Style 326 hanger is used in applications where hot materials are con-

veyed which can bring about linear expansion of the conveyor sc:rew. The han-ger support bar is free to slide on angle guide bars to compensate for unequalexpansion between the trough and conveyor screw. Its construction is similarto Style 226 and thus maintains all the advantages thereof.

Style 30:

The Style 30 hanger is used when mounting a hanger to the top flanges ofthe trough cannot be achieved. It mounts to the non-carrying side of the troughand thus minimizes obstruction to the flow of material.

Flared Trough Hangers:

Flared trough hangers are available in any of the above configurations foradaptation to flared troughs as shown on page 76 of this manual.

Hanger Bearings:Hanger bearings of oil impregnated wood, UHMW polyethylene, nylon, hard

iron or babbitt can be supplied for Styles 226, 220, 326 and 30. Numerous othermaterials are available for special applications as shown on page 25 of thismanual. Style 270 on the other hand is available using only the ball bearing

assembly.

TROUGH ENDS

Trough Ends With Feet:

Trough ends with feet are the most commonly used trough ends. Thebottom flange foot is used to support the conveyor and is complete withslots for bolting the unit in position. All holes are jig punched to assure aproper fit to the trough end. The flange bearing is bolted in position tothe trough end with a bolt pattern dependant on the style of bearing used.It is therefore necessary to stipulate the type of bearing when ordering.

Trough Ends Without Feet:

Trough ends without feet are of identical construction to those withfeet with the exception that the trough is fixed in position using separateflanged feet or saddles. As with trough ends with feet, it is necessary tospecify the type of bearing used when ordering.

Outboard Bearing Trough Ends:

Outboard bearing trough ends are used in conjunction with split glandor packed gland seals. A shelf welded to the trough end acts as a pe-destal to which the pillow block bearing is bolted. The shelf type troughend is interchangeable with all other trough ends and is particularilysuitable for applications conveying hot or abrasive materials from whichthe bearing should be isolated. It is necessary to specify the type of bear-ing used when ordering.

Double Outboard Bearing Trough Ends:

Double outboard bearing trough ends are used in conjunction withtwo pillow blocks for applications that require extreme rigidity and con-centricity of the conveyor shaft. They are most often used at the driveend when a heavy shaft mounted speed reducer is being used to drivethe conveyor. As with single outboard bearing trough ends it is necessaryto specify the type of pillow block used when ordering.

Discharge Trough Ends:

The discharge trough end is used when material is to flow directlyfrom the end of the trough. Due to its size, it is necessary that thetrough' loading not exceed 45% or it will restrict material discharge. Itis available with either a bailor a sleeve type flange bearing which mustbe specified at the time of ordering.

TROUGH END BEARINGS

Ball Bearing Flange Unit:

Flange bearings of this type are commonly used on thenon-thrust end of a screw conveyor. The gray iron housingincorporates a heavy duty single row ball bearing that is self-aligning and has a good radial load capacity.

Roller Bearing Flange Unit:

Roller bearing flange blocks of this type incorporate aheavy, rugged gray iron housing and two tapered roller bearings.The units have a high radial load rating with good thrust capaci-ties. They also will handle slight angular shaft mislalignment.

Sleeve Bearing Flange Unit:

This is a babbited type flange bearing that is used in appli-cations that do not require or are unsuitable for conventional ballor roller bearings. They have no misalignment capabilitieshowever do have good radial load capacities.

Roller Bearing Pillow Blocks:

Are of similar construction to the roller bearing flange unithowever are used in conjunction with shelf type trough ends.

TROUGH END BEARINGS

Sleeve Bearing Pillow Blocks:

Are of similar construction to the sleeve bearing flange unithowever are used in conjunction with shelf type trough ends.

~

Type E Thrust Bearings:

The Type E bearing is the most commonly used thrustbearing and is designed to handle medium to heavy thrust loadsin either direction while maintaining good radial load capacities.Thrust is created opposite to the material flow in a screwconveyor which will cause accelerated component wear if notcontained. It is thus advjseable to incorporate a thrust bearing,preferably at the drive end, to keep the conveyor screw in tension.The thrust is contained by snap rings on the shaft on each side ofthe bearing assembly.

,...~

~

Type H Thrust Bearings:

The Type H thrust bearing is used for cases in whichextreme thrust loads are encountered. The shaft is shoulderedand set between two high capacity roller bearings in order toabsorb thrust in both directions. The assembly incorporates liptype seals within the housing thus eliminating the need for exter-nal trough end type seals.

Collar & Washer Thrust Assemblies:

Assemblies of this type are used in conjunction with sleevetype bearings in applications where light thrust loads are encoun-tered. The collar, washer and grooved shaft are mounted outsidethe trough and are intended for use at the discharge end of theconveyor with the conveyor screw in tension.

Bronze Washer Thrust Assemblies:

The bronze washer assembly is mounted inside the con-veyor trough at the inlet end and is designed to handle light,compression thrust loads. It consists of a bronze washer moun-ted between two machined steel washers fitted between thetrough end and pipe. Due to its interior location it is exposedcontinuously to the material being conveyed and thus in someinstances has a limited life.

TROUGH END SEALS

Packing Seal Housing:

Packing type seals are used in conjunction with waste packing or acartridge type lip or felt seal. They bolt between the trough end and theflange bearing however can be mounted independently for use with ashelf type trough end. The housing incorporates a wide opening at thetop to facilitate waste repacking along with strategic holes for oiling.They simply but effectively isolate the bearing from the trough end andpotential material carry through around the shaft.

Plate Seal:

Plate type seals are a simple, economical yet effective device whichcan be bolted between the trough end and flange bearing or used inconjunction with a shelf type trough end. Standard units incorporate abraided packing material that is compressed around the conveyor shaftwhen the seal is tightened in position to the trough end, however can alsobe supplied with a lip type seal if required.

Split Gland Seal:

Split gland seals use a braided packing material which is compres-sed between a split adjustable housing to facilitate packing replacementand regulate the compression applied to the packing. They can be moun-ted either inside or outside the trough and are generally used in conjunc-tion with a shelf type trough end.

Packed Gland Seal:The packed gland seal is used for severe applications that require ef-

fective sealing under all conditions. They can be used under both positi-ve and negative pressure and can seal the trough either internally or ex-ternally. A braided packing media is compressed around the shaft bytwo compression bolts which can be used in conjunction with lanternrings and/or grease fittings depending on the application. Due to theirconfiguration they can only be used in conjunction with a shelf type troughend.

TROUGHS

Formed Flange Troughs:

Formed flange troughs are the most commonly utilized typeof U- Trough. The top flange is formed from the same steel as thetrough thereby providing rigid onepiece housing section. Theend flanges are jig welded in special positioning machinery forperfect alignment with the other sections.

Angle Flange Troughs:

Angle flange troughs are fabricated using a heavy structuralsteel angle welded flush with the top of the trough edge. The weldsare intermittent however can be continuous seam welds in theevent that dust tight construction is required. The end flanges arejig welded in special positioning machinery for perfect alignmentwith other sections.

Channel Troughs:

Channel troughs are commonly utilized for conveyorshaving long distances between conveyor supports. The troughsides are fabricated of structural steel channels that impart greatrigidity to the trough. A contoured section is bolted or clampedin position. Troughs of this type are useful for abrasive applica-tions that require frequent replacement of the lower trough sec-tion.

Drop Bottom Troughs:

Drop bottom troughs are used in applications where quickconvenient access to the conveyor interior is required. The bot-tom trough consists of rigid upper side channels to which alower contoured section is attached. One side of the lowercontoured section is hinged while the other is attached usingspring clamps or other quick opening clamps.

Flanged Tubular Troughs:

Tubular housings are inherently dust and weather tight.They are most often used when full cross sectional loads must bemaintained such as in steep angle conveying. The trough sectionconsists of two semi-circular halves bolted together along theflanges to form a tubular housing.

Solid Tubular Troughs:

The solid tubular housing maintains all the characteristics ofthe formed tubular housing with the exception that it is rolledfrom a single plate and continuously welded at the seam for dustand weather tightness.

72

Formed Flange Rectangular Troughs:

Formed flange rectangular troughs are formed from a singleplate and are commonly used for highly abrasive applications. Thematerial builds up to form its own trough bottom thl.Js preventingdirect abrasion against the trough wall.

Angle Flange Rectangular Troughs:

Angle flange rectangular troughs are identical to the formedflange type with the exception that the flange consists of a heavystructural steel angle welded flush with the top of the trough edge.The welds are intermittent however can be continuous seam weldsin the event that dust tightness is required.

Flared Troughs:

Flared troughs are primarily used to handle sticky or slightlyviscous materials and are used in conjunction with ribbonconveyors. The flared trough sides improve the feeding andconveying action in such cases. The flanges are formed from thesame plate as the trough and the end flanges are jig welded toensure perfect alignment.

End Flanges:

Trough end flanges are cold formed on special machineryand jig punched to assure dimensional accuracy in order thattrough sections will align perfectly.

,

Trough Saddles & Support Feet:

Trough saddles are used to support the trough at interme-diate points between trough flanges and are normally weldeddirectly to the trough. Support feet on the other hand are boltedto the end flange and are used to support the trough sections.
