Disc Screen (RDS) by Jeffrey Rader Brand

For removing oversized rejects from unscreened wood chips, hog fuel or bark, the Jeffrey Rader Disc Screen is the undisputed workhorse of the industry.


Wood chip and hog fuel processing are typically a 24-hour-a-day operation. That’s why you need a screen on which you can depend. The Jeffrey Rader RDS is engineered for rugged, nonstop service with only routine maintenance.

Advantages & Benefits:

  • All service points and components are easily accessible
  • Material is continuously moved across a series of rotating multi-toothed discs so small particles are shaken loose, larger matter moves on
  • Openings between discs can be set to screen out glass, grit, ceramic material, aluminum and large fibrous matter
  • Discs and spacers are removable and can be changed in the field
  • By installing different length spacers, the action of a disc screen unit can be modified onsite
  • Compact design for minimum space requirements
  • Energy efficient operation
  • Self-cleaning for minimum downtime, higher volume
Technical Data
  • Screen is manufactured under ISO 9001 specifications
