• A conveyor system is a common piece of mechanical handling equipment that moves

materials from one location to another. • According to Sclater, conveyor systems can be

divided into two classes: those that are part of a machine for processing product, and

those that move products in various stages of fabrication. 

DEFINITION

TYPES OF CONVEYORSMAMAMIAAAAAA

SCREW CONVEYORS

• The screw conveyor usually consists of a long-pitch plate –steel helix mounted on shaft or spindle carried

in bearings within U-shaped trough.• According to Hudson, for many functions, it is the

best type of conveyor.

FLIGHT AND APRON CONVEYORS FLIGHT CONVEYORS

The flight conveyor has an endless chain or twin chains passing around sprockets at the head and

foot ends, with spaced transverse scrapers or “flights” which push the material along a trough.

Types of flight conveyor

I. SCRAPER FLIGHT

II. SUSPENDED FLIGHT

III.ROLLER FLIGHT

IV.ROLLER CHAIN

V. DRAG CHAIN

Flights are drawn along the trough bottom. The figure below is a single strand, scraper flight conveyor.

SCRAPER FLIGHT

SUSPENDED FLIGHT

This type has wearing shoes attached to the flights to carry them clear of the trough along the carrying run, and

support them along the return run. The figure below is a double-strand, suspended flight conveyor

ROLLER FLIGHT

It is similar with the suspended flight conveyor except that, rollers are substituted for shoes.

ROLLER CHAIN

The figure below is a double strand with roller chains to carry the flights.

DRAG CHAIN

Such conveyors do not have flights as the open links serve to

move the material.

APRON CONVEYORS

The alternative to a flight conveyor may be an apron conveyor.

The apron conveyor consists of overlapping beaded steel pans supported between or

mounted upon two strands of roller chain, and with the usual head and foot assembly

BUCKET ELEVATOR

A bucket elevator, also called a grain leg, is a mechanism for hauling flowable bulk materials (most

often grain or fertilizer) vertically.Vertical elevators depend entirely on the action of

centrifugal force to get the material into the discharge chute.

UNIT LOADS

The term unit loads is generally use to cover the handling of boxes, bags, packaged materials, castings, paper rolls

and in general integrated items as distinguished from pulverized, granular, and lumpy bulk materials.

SPIRAL CHUTE

Is the simplest method and lowest cost when a direct lowering of package or boxed materials is involved.

SPIRAL CHUTE

Either gravity-roll or power-roll conveyors may solve the problem of horizontal and inclined

movements more economically than is possible with any other machines

When two or more roller conveyors are tributary to a trunk line, it is necessary to prevent

collisions by an interceptor.

ROLLER CONVEYORS

Gravity conveyors are best adapted for boxes or cartons with unyielding riding faces, approximate uniformity on weight,

and not over 100 lb. each.

Pallet Chain Conveyors in the foreground is a rotating disc which, with guide plates, serves to shift the bottles from the

approach line to the reverse line.

For unit loads, it may be similar to the standard flat-belt conveyor, but with closely spaced carrying idler rolls. Almost any type of unit loads, not destructive to the belt, may be so handled.

BELT CONVEYORS

The Vibrating Trough, sometimes referred to as grasshopper conveyor is the best machine to move sustained output of fragmentary materials.

When stacks or batches of magazines are to be lifted or lowered, there are several types of tray elevators or lowerers available.

OVERHEAD TRAMS AND CONVEYORS

Manufacturing operations, may preferably be by overhead transport, keeping the aisles clear and eliminating damage to the floors

The tramrail, or monorail system, consists of a carrier suspended from an overhead I-beam track or runway usually suspended from the ceiling beams except in the larger units wherein it is supported below.

• Overhead conveyors, or trolley conveyors, consists of a power-propelled chain travelling at moderate speed

• suspended by trolleys from a suitable track, and• provided with attachments of various forms adapted to

the work to be done.

CONTINUOUS-FLOW CONVEYOR

The continuous-flow conveyor is a machine in which the material moves slowly within a duct as a continuous core

PNEUMATIC AND HYDRAULIC CONVEYORS

o The pneumatic conveyor depends on a high-velocity air stream to move material in about the same manner as the wind

o The hydraulic conveyor is a system for handling material; refuse is flushed from a hopper or slag tank to a grinder which discharges to a

pump for conveying to a disposal area

CONVEYOR CONTROLS

Photoelectric control is the control of a circuit or piece of equipment by changes in incident light.

Applications of photoelectric control includes:

automatic weighing and fillingoperator safeguard sortingheat treatment jam detection automatic inspection

o A conveyor system is often the lifeline to a company’s ability to effectively move its product in a timely fashion

o Steps to ensure Peak Performance: inspectionsclose monitoring of motors and reducers keeping key parts in stockproper training of personnel

o Increasing the service life of your conveyor system involves: choosing the right conveyor type, the right system design and paying attention to regular maintenance practices.

CONVEYOR CARE AND MAINTENANCE

o Here are six of the biggest problems to watch for in overhead type conveyor systems including I-beam monorails, enclosed track conveyors and power and free conveyors
