Wash Press Compactor WPC

  • Modern construction from robust certified stainless high quality materials.
  • Double trough gives high torque resistance and maximum dewatering capability.
  • The double trough allows for long inlet lengths. Saving additional conveyors. And
    enables optimum perforation area of the inner trough for high dewatering and good drainage.
  • Robust wear steel lined screw and thick wear bars gives wear resistance and handles high compaction forces.
  • Separate thrust bearing and flexible coupling compensates for screw angle variations and absorbes press forces protecting the gearbox.
  • Compact design with selectable drive unit gives flexibility.
  • Enclosed, safe & hygienic with easy to open access doors.

Wash Press Compactor WPC is a screw press for washing, compaction och conveying of screenings and wet waste. WPC forces the material into a pipe system and can be combined with Back Pressure Shredder BPS which gives heavy mechanical agitation for high washing, compaction and dewatering. The screw flights gives a pulsating treatment of smaller portions which also increases washing, dewatering, & compaction. WPC has 15-30mm screw flight thickness in the transport zone and 30-60mm in the wash compaction zone. WPC often has double the thickness, strength and wear capabilities compared with others. We recommend spiral wound steel screw rather segment welded stainless flights due to double thickness and much higher wear resistance. WPC has stainless steel high quality valves as standard where others use brass.
