Introduction of a ProGrade™ screen to your production processes

off ers:

1/ Increased acceleration and performance

2/ Quick and easy customisation of screen media to suit your

application

3/ Superior wear resistance, minimising maintenance requirements and

maximising plant production.

The CDE ProGrade™ Screen is an

inclined circular motion screen

designed to cope with the

harshest conditions.

ProGrade™ Applications

The ProGrade™ screen range is built for general quarrying applications and provides a separation range of between 2mm and 140mm.

Our screens can be applied at many points in your processing operation:

• For screening after primary or secondary crushing

• To divide fl ows within a processing system

• For fi nal screening of fi nished fractions

Off ering a broad range of both dry screens and rinsing screens the ProGrade™ range can be applied in the processing of a variety of materials including:

• Sand & Gravel• Crushed Rock• Construction & Demolition Waste

Material• Top soil

Many features off ered as optional extras from other suppliers are

included as standard on the ProGrade™ range as we seek to bring

the most effi cient, high performance screening system available to

the world market. All models within the ProGrade™ screen range

have been fully FEA verifi ed using the very latest FEA technology.

Designed with washing in mind

The P2-75 and P3-75 models are designed with their primary function to be as a rinsing screen. Other ‘rinsing screens’ are all too often dry screens with the crude addition of a few spray bars

There are a number of features of the ProGrade™ screen range which ensure its performance as a rinsing screen is far in excess of other screens available on the market:

Individually controlled spray bars

The water supply to each spray bar can be shut down individually to allow for easy modifi cation to the washing system depending on the specifi c requirements of the material being processed.

Rotating spray bars for ease of access

The spray bars on the ProGrade™ screen rotate allowing easy operator access for replacement of screen media. This reduces plant maintenance time and allows for quick and easy changes to the screen confi guration to allow for variations in fi nal product requirements to be easily accommodated.

Each spray bar nozzle is also individually adjustable to allow for appropriate positioning relative to the material on the screen deck.

PROGRADE™ Key Benefi ts


Stand alone spray bar assembly

The spray bar assembly is not rigidly fi xed to the screen box but is an entirely independent structure. This eliminates vibration and the associated risk of plant failure.

A safer, cleaner, more productive site

Splash prevention over decks and specialist spray bar seals reduce the risk of both material and water loss resulting in a safer, cleaner, more effi cient operation.

High specifi cation bearings and unique bearing protection

Market leading SKF bearings are used as standard on the ProGrade™ screen range and a unique double seal arrangement prevents contamination of the bearings during plant operation.

The use of high specifi cation bearings, coupled with the unique bearing seal arrangement:

1. Minimises risk of plant failure2. Reduces time and cost of plant

maintenance and repair3. Ensures maximum production from

your screening plant

Replaceable rubber lined feed impact zone

This minimises the impact of material on steel and its position also ensures that material is delivered to the very back of the screen, maximising the available screening area.

Easily replaceable rubber lining also reduces the time required for plant maintenance therefore increasing plant productivity.

Rubber marshmallow screen mounts

These harness the vibration within the screen and ensure the maximum amount of energy is transferred to the material rather than the supporting structure as happens when traditional steel springs are specifi ed.

This feature reduces oscillating variable stress which is one of the major causes of plant failure.

Rosta tensioned drive unit for increased belt life and effi ciency

As belts are held in constant tension they are not subjected to any shocks as the screen box rotates resulting in increased plant life and reduced maintenance costs.

Bolted Design signifi cantly reducing stress on the structure and increasing plant life

Adjustable RPM allows for variations in feed to be easily accommodated.

Designed to accommodate a range of diff erent screen media with no modifi cations required to the screen box.

PROGRADE™ProGrade™ P2-75 Rinsing Screen

PROGRADE™ProGrade™ Rinsing Screen Feeding RotoMax™ Logwasher

Lattice design screen box

Reduces the mass of the screen box and ensures more energy is transferred to the material ensuring superior screening performance.

Adjustable RPM allows for variations in feed to be easily accommodated

The ProGrade™ screen range has been designed to operate at the centre of its maximum bandwidth off ering you the maximum range between natural frequency nodes.

This allows for operating speeds to be increased or decreased signifi cantly and without risk of plant failure to allow for the production of diff erent material grades or the processing of diff erent materials.



Easy accommodation of a variety of screen media

The screen media on the ProGrade™ screen range can be changed quickly and easily with no modifi cations required to the screen box. The addition of hexagon punch plates allow for easy transition from polyurethane panels to side tensioned wire mesh if required.

The ProGrade™ screen range can accommodate:

• Isenmann Polyurethane modular panels• Rubber• Isofl ex polyurethane coated wire mesh• Side tensioned wire mesh

Any combination of these can be used on the ProGrade™ screen range which also allows for diff erent screen media to be used on the same deck.

Cartridge design of screen decks

This prolongs plant life as it eliminates wear on otherwise welded joints.

Revolutionary shaft design

The ProGrade™ range includes a unique hollow shaft design which signifi cantly reduces the mass of the shaft assembly while still generating the same force as a traditional solid shaft.

The high energy shaft design on the ProGrade™ range ensures more energy is transferred into the material, resulting in a lower power requirement than in comparable screens.

Bolted, not welded

Welded structures induce higher stress levels than bolted structures. Throughout the ProGrade™ range there is minimal use of welding which signifi cantly reduces stress on the structure therefore increasing plant life.

Superior wear protection

The shaft assembly and all cross members are rubber lined as standard off ering increased wear protection and reduced ongoing maintenance requirements.

Standardisation of spares with EvoScreen™ dewatering screen range

A common set of spares exists ensuring:

• Minimum number of diff erent parts need to be held in stock

• Reduced time required for operator maintenance training

• Reduced time spent on plant maintenance

Easy, Safe Access for Operation & Maintenance

The inclusion of fully galvanised walkways and access stairs as standard on the ProGrade™ sets it apart from other screening systems.

• Safe and easy access for operators and maintenance personnel.

• Minimises time required for maintenance

All walkways are fully compliant with European Health and Safety Specifi cations.
