Introduction

4. Service: The screening media and the vibrating screen must be defined as a complete screening system. TYCAN understands that responsibility and as a result offers far reaching services, such as the self developed vibration anal-ysis. Using such milestone technologies we are today capable of ensuring complete synchronization between screening media and vibrating machine with the help of automati-cally generated improvement recommendations. To ensure the quality of the recommen-dation results, we again re-quire the particle analysis and thus the screening circle closes to form a complete rotation.

3. Vibrating Screens: The particle sizes of the feed material as well as the required cut sizes determine the necessary drive tech-nology and physical size of the vibrating screen. TYCAN s̓ engineering depart-ment is a very international team. As a result the customer benefits from this wide range of experience and process studies with screening solutions that are extraordinary and unprecedented in the history of the screening industry. Using tools such as FEA and 3-D CAD systems, TYCAN s̓ promise is to develop customized solutions according to product application and customer specification.

2. Screening Media: The results of the

particle analysis and the material charac-

teristics determine the opening and the com-

position of the screening surface. TYLER offers a

full line of screening media, starting with woven wire cloth,

engineered rubber and polyurethane systems to self cleaning screens and per-

forated plate. TYLER understands the impact media changes can have on protecting the vibrating

screen itself.

1. Particle Analysis: the basis for any screening process is the understanding of the size distribution within the

feed material as well as the desired product. TYLER offers all aspects of particle

analysis, beginning with standard sieves over traditional laboratory

shakers such as the famous “ROTAP” to the technology

of Computerized Particle Analysis (CPA).

Eccentric Shaft Systems(4-bearing Technology)

The N-CLASSThe TYCAN N-Class is commonly used as a primary screen tar-geted at increasing the throughput and the effi-ciencies of the primary crusher in very heavy duty and aggressive environments. Capable of handling particles as big as 78” x 39” x 39” and screening at cut sizes of ½” to 12” it is ideal for very demand-ing industries such as mining or crushed stone.

This operation prin-ciple consists of the use of a shaft and four bearings. The vibra-tion motion is worked

into the shaft in form of single eccentricity, allowing for equip-ment operation with consistent amplitude, independent of the load fed to the screen.

Due to the constant dynamic operating conditions and conse-quently the very high G-Forces generated by the technical principle of the vibrating screen, product particles are consistently launched out of the classification openings of the media creating a self-cleaning effect, which minimiz-es material clogging and pegging.

PRINCIPAL CHARACTERISTICS:• Consistent amplitude• Constant dynamic, load independent operating

conditions, • Adjustable frequency• Dry and humid classification• Cuts of up to approximately 12”• High classification capacity and better classifica-

tion efficiencies• Use of perforated plates up to 4” with conical

opening as classification media• Allows for various classification deck configura-

tions• Allows for the classification of viscous and

sticky products• Does not transmit vibrations into the structure • Width of up to 8 ft.• Length of up to 22 ft• Optional full or partial dust enclosure• Allows for immediate stoppage (either by elec-

tric brake or by reversal) eliminating residual vibrations

Counterbalanced double eccentric shaft assembly

The F-CLASSThe TYCAN F-CLASS is the number one vibrating screen for classification in the heavy mining, mineral and crushed stone indus-tries. The positive circle-throw motion of the F-CLASS is devel-oped by a counterbalanced double eccentric shaft, which is supported by four double spherical roller screen bearings. Rubber mount-ing units dynamically balance by isolating the vibrating body from the stationary base frame. The shaft is supported on the base by side arm assemblies that are also isolated on rubber mounting units. The F-CLASS free floating action permits the shaft to find its natural center of rotation without strain or thrust on the bearings. This feature minimizes maintenance and down-time and prolongs the life of the bearings.

5

The T-CLASSThe TYCAN T-CLASS vibrating screen with field proven features makes it a versatile performer. It is designed to be a rugged dependable vibrating screen for use in the screening of a wide variety of materials.

The circle throw motion of the T-CLASS Series is developed by a counterbalanced shaft assembly, which is supported by two double spherical roller screen bearings. The circle throw action has proven to be very effective in moving coarse material to the top of the bed so that the fines and near mesh particles may pass through the media openings. The T-CLASS Series provides fast and accurate sizing of materials.

The T-CLASS Series modular design and the use of standard components result in savings because TYCAN fabricates and assembles machines cus-tomized to the application by using standard stock components. This standardization of components also results in readily available spare parts.

The T-CLASS simple design combined with its rugged construction results in minimum mainte-nance and downtime.

ed, easily interchange-able exciter units

• Bearing lifetime of up to 50,000 (application dependant)

• Adjustable frequency at speeds of 750 to 1050 RPM

• Versatility in stroke by weight additions to the exciter counterweight

The XL-CLASS

Todayʼs markets have increasingly been demanding higher production rates in form of bigger machines as well as superior machine availability. Traditional shaft driven technology reaches its limitations at a determined width due to the mechanical deflection of the shaft resulting in unaccept-able bearing lifetimes. TYCANʼs solution to the marketʼs demands and the technological limitations of the shaft technol-ogy is the exciter driven XL-Class. The exciter is a completely incased drive unit consisting of short shafts supported by closely positioned bear-ings. Mounted on a spe-cially designed over head bridge the exciter tech-nology allows TYCANʼs XL-Class to be built at widths in excess of 8ft addressing the market need for bigger machines. Due to carefully chosen bearing sizes in combina-tion with maintenance

friendly lubrication via oil the demand for avail-ability is addressed by bearing lifetimes as high as 50,000 hours (applica-tion dependant).

Not only does the XL-Class set new standards in its drive principle but also in its body design. Enabling forces of more than 5g (application dependant) the XL-Class is engineered using state of the art Finite Ele-ment Analysis technol-ogy (FEA). FEA enables structural calculations by simulating the machineʼs dynamic behavior in form of a 3D model.

The results of the simula-tion allow the determina-tion of resulting tensions and natural frequencies to assure a technologically optimized and economi-cally sound design.

Traditionally developed for the mining indus-tries such as copper and iron ore the XL-Class is also finding its way into

construction materials such as sand, crushed stone and aggregates due to its impressive payback and maintenance friendliness.

Horizontal Screening Systems

The XL-CLASSBananaCertain applications call for versatil-ity in changeability of screening surface angles. TYCAN answers this market demand with the XL-Class Custom Slope Deck, designed to provide high yield and efficiency in screening.

Larger angles of inclination in the feeding area offer a speed gain in the material flow, which assures a reduced height in the screening layer and allows fine materials to easily pass through the screening media. Subsequent changes in the inclina-tion angles of the media along the screen structure assure a reduction of flow speed allowing the final layer thickness to increase, thus insuring accurate sizing performance at the screenʼs discharge end. The Custom Slope Deck screenʼs mechanical structure is strong and solid and entirely equipped with Huckbolts, providing high operating capacity and low maintenance cost.

PRINCIPAL CHARACTERISTICS:

• Linear Free Vibrating System with “Exciters”

• Strength and Reliability• High efficiency in screening• Easy to operate and to install

• Material in non-laminate format • Designed specifically for granu-

lometric applications with high concentrations of under-sized materials

Drive system: The drive system of the Banana vibrating screen consists of exciters which are essentially composed of counterweights attached to a rigid shaft that seats in special bearings. These bearings were developed for vibrating equipment and have a useful life of 50,000 working hours or more (application dependant).

De-Watering Systems

The D-CLASSThe TYCAN D-Class was mainly conceived for the iron ore industry in order to minimize the per-centage of water residue in the product, enabling a substantial improvement in the handling, transport and piling up of ore.

Used for dewatering of various products, the equipment works to allow for better material compact-ing and consequent water expul-sion.

Depending on the machine size and application, one of the free linear motion drive assemblies is used.

Apart from the characteristics of the free linear motion screen, the dewatering screen has the follow-ing features:

PRINCIPAL CHARACTERISTICS:

High Speed Screening Systems

The S-CLASSS-CLASS is a versatile high speed circle-throw movement machine designed for medium and fine screening of very dif-ficult wet or dry materials such as sands, gravel, lime, coal, chemicals, fertilizers, gold and metal ores.

The S-CLASS is a tough two bearing machine with flexibility to meet de-manding and changeable screening conditions.

The vibration of the S-CLASS is developed by a counterbalanced shaft assembly which is supported by two double spherical roller screen bearings mounted in duc-tile iron bearing housings at each end of the vibrator assembly.

The vibrator is located over top of the vibrat-ing screen body and is demountable for service. The circle-throw motion produced by the vibrating head is transferred into a forward inclined ellipti-

cal action on the screen surface at the feed end and into a backward inclined ellipse at the discharge end. This special design creates high transport velocities at the feed end and lower ones at the discharge end. This causes a quick and equal distribu-tion of the material on the first third of the screen deck and a sharper screen-ing at the last third.

Hydro - Clean

Before

Often customers not only require screened product but cleanly screened products, TYCAN has developed a technology capable of cleaning material mixtures with particle sizes ranging from 0-150 mm, with the use of high pressured water: The TYCAN Hydro Clean.

The result of this technological quantum leap is a high pressure cleaning system for production rates from 50 to 400 tons of output material per hour. Designed similar to a household washing machine the contaminated material is fed into an actual washing chamber by a hopper. Inside the machine the material builds a column standing on a conveyor belt, the speed of which controls the through-put of the material and the washing cycle. To protect the chamber, its inside is lined with standard polyurethane screening panels allowing dirty water to escape and be returned to a settling pond. The constantly recycled water is fed to jet valves, which rotate at the top of the washing chamber. As a result the water is injected at rates from 800 to 2000 PSI and intensely interacts with the contaminated product by blowing onto the particles and penetrating porous areas, which friction based wash-ing technology could never reach. This means the Hydro Clean is capable of offering never before seen cleaning degrees. Products thought to be impossible to clean can now be sold at premium prices.

ADVANTAGES:

• Highest cleaning results possible• Lowest water consumption available• No tool wearing – water jet• The water jet reaches directly the material to be

washed• The drum is coated with PUR-standard screens• Optimum material adaptation

Our aim is not only to satisfy our customers with our machinery, but to provide complete solu-tions. Therefore, the services of TYCANʼs engineering department are not limited to machines but allow the following services:

Engineered Screening Studies Running different R&D projects and design studies on TYCAN® machines our engineers provide a complete process analysis in the form of an Engineered Screening Study (ESS). Utilizing our own programmed soft-ware and digitized tools, TYCAN® Engineering can provide complete screening and crushing studies for existing or future projects ranging from a one-deck system to high-ca-pacity processing plants.

The basic data for such Engineered Screening Studies (ESS) are provid-ed by the customer on-site during the visit of our TYCAN engineer. The data is used to build a computerized

model of the customerʼs existing or new plant and operation. Depend-ing on the customerʼs improvement targets, the impact of changes to plant settings can be tested by the model in a fast and efficient manner, revealing the correct and necessary adjustments in terms of process opti-mization and process design.

To visualize the different scenarios, computerized flow sheets are devel-oped which demonstrate the related efficiencies and/or usage of the crushing and screening equipment under the different settings.

Finally, the customer receives a precise and accurate report docu-menting the findings, the results, the

calculations, and most importantly the recommendations and proposals for the plant layout.

These recommendations are backed by our experience and are evalu-ated and proven where applicable in collaboration with the customerʼs structural engineers. All recommen-dations to design changes on existing plant structural work show the best accommodation of new or moved equipment and enable the best flow of material under existing circum-stances.

Vibration Analysis Self developed and Custom pro-grammed for vibrating screens, TY-CANʼs Vibration Analysis Service (VA) allows for easy “hook-up” of a lap-top computer to your vibrating screen on site by TYCAN´s trained technicians. Based on the data the performance of vibrating screens can be evaluated in terms of proper speed and stroke. Machine and screening media are synchronized by automatic improvement recom-mendations. The determination of critical and developing faults such as bearing failures, spring problems, loose machine components or other are also possible.

The measuring system features up to 8 accelerometer channels allow-ing a full scale screen performance analysis. The information allows for on-screen display of orbit plots, peak-to-peak and average accelera-tions and displacements as well as RPM computing and FFT analysis.

The results of the tests are put into a valuable and easy to understand customer report. This document not only outlines the analyzed data, but also makes recommendations on how to improve screen performance based on different settings or new parts. Rebuild Programs Not only does TYCAN® build screening machines to last, but we can rebuild them to last even longer. Over time and years of constant use even a TYCAN® screen can show its age.

Now with the TYCAN Rebuild Pro-gram you can reduce maintenance costs and even increase your produc-tivity by avoiding costly replace-ments. Our Rebuild Program can be accomplished on-site to minimize the time your machine is down.

You can expect prompt on-site evaluations, a detailed itemized re-port and quotation, scheduling of the rebuilding process and delivery to customer site. A TYCAN® Service Representative will be on-site to supervise start-up. Preventative Maintenance Todayʼs market demands for eco-nomical products and high produc-tion efficiencies make it necessary for our customers to reduce machine downtimes to a minimum. Whether for regular scheduled maintenance routines or in emergency cases the equipment must be ready to produce again as fast as possible. As a screen-ing solutions provider TYCAN has recognized the necessity for a new service.

Our Preventative Maintenance Program (PMP) is designed to considerably cut the operation and maintenance costs for our custom-ers´ vibrating screens and media.

Even though emergency situations can never be fully avoided they can be minimized with proper, manufac-turer-supported maintenance. But in addition continuous costs for spare parts and service can be reduced sig-nificantly with the proper program.

The benefits of the general services covered by a preventative TYCAN maintenance program include the combination of our ESS, Vibration Analysis and our Rebuild Program. As a result our customers receive the following advantages:

1. Reduced Service Rates 2. Inspection and Vibration Analysis 3. Sizing Assistance 4. Regular Maintenance & Media

Seminars 5. Rebuild Program Management 6. Spare Parts Inventory Manage-

ment 7. Reduced Spare Part Prices
