Disc Screen
DISC SCREEN
For the separation of overlengths
Disc screens by Rudnick & Enners are suitable for the separation of oversized particles from the material flow. For example, it is possible to separate oversized particles in biomass transport at minimum space requirements and energy input. Disc screens are characterized by their high screening/throughput rate as well as ease of maintenance.
With a highly diverse range of sizes and designs, Rudnick & Enners disc screens can be individually adapted to customers’ requirements. Bolted disc segments increase the ease of maintenance and can even be retrofitted if material properties or requirements change.
The light version of the disc screener is particularly efficient at separating overlengths from single materials such as dry stabilate (clean fuel for power plants, etc. derived from domestic waste), bark, green waste and fresh wood.
FULL RANGE OF SIZES & CONFIGURATIONS
Highly efficient and cost-effective for high volume coarse screening applications
Increase throughput and reduce Grinder maintenance by removing overs, chunks, splinters, and trash
Low speed, smooth operation eliminates the need for special support structures or foundations
Agitation action of discs improves screening efficiency
Modular side sheets allow for quick and easy maintenance access
Central lubrication station makes it easy to service
Solid through, large diameter shaft assemblies contribute to a long operating life
WSM’S DISC SCREENS ARE AN EFFICIENT AND COST EFFECTIVE CHOICE FOR HIGH VOLUME, COARSE SCREENING APPLICATIONS.
- WSM Disc Screens operate by accepting material from an infeed device
- As material slides down the chute, smaller material (“fines”) fall through the disc openings
- Later material (“overs”) is transported to the end of the screen and transported to the end of the screen
- “Overs” can be discharged into a Grinder, Hog, Hammermill, No-Knife Re-Sizer, or reject conveyor

STANDARD & OPTIONAL FEATURES
Disc Profile: Various disc profiles are available to meet specific application needs
Orientation Rolls provide tight disc spacing on initial rotors to transition infeed material on to the main screen area
Anti-jam Control: Detects jam up though current sensing on drive motor. Provides controls to reverse and clear the jam automatically
Motion Switch: Detects motion and zero speed conditions
Top Covers: Provides enclosure over to of screen for dust control and safety purposes
