Linear Motion Screens

  • High fluid capacity
  • Ideal for dilute slurries and/or low amounts of oversize such as scalping or trash screen applications
  • Appropiate for removal of grit or other contaminants from viscous slurries
  • Screen openings can range from 3/8" (10 mm) to 400 mesh (38 microns)
  • Low headroom requirements
  • Uniform straight-line conveying action
  • High open area urethane screen surfaces or various woven wire screen designs minimize or eliminate screen blinding

Derrick linear motion screens are ideally suited for dilute slurries, solids recovery, dewatering, and slurries with low amounts of oversize such as scalping or trash screen applications. With its high fluid capacity and low head room requirements, Derrick linear motion screens are available in dual and single motor configurations. The dual motor version incorporates two Derrick vibrating motors rotating in opposite directions, causing the screen frame to vibrate in a linear or straight-line motion perpendicular to the base plane of the motors. The more economical single motor version develops linear motion through the use of a unique, patented, pivoting motor mount system.

Depending upon the application, the screen frame can be positioned from +10° to -15°. Maximum fluid capacity is achieved in the uphill position, causing the formation of a pool at the feed end of the machine. The head or pressure from the pool increases fluid throughput. The linear motion of the screen frame efficiently conveys the oversize particles out of the pool area where they are then dewatered and discharged.
