Match the machine to the duty.

MATERIALS & DUTIES
  • Barrel products: plastic, metal and paint barrels, IBC containers and bins.
  • Mixed solid waste: bulky, domestic, industrial and selected garden waste.
  • Plastic products: pallets, bottles, frames, blocks and containers.
  • Metal products: aluminum castings, filters, cans and selected automotive parts.
  • Paper: newspapers, cardboard, corrugated board and office paper.
  • Electronic appliances: refrigerators, circuit boards, housings and optical discs.
  • Glass products: glass wool, bottles and selected glass-containing waste.
  • Paper-mill waste: light rejects, pulper rope and production residue.
EXPECTED OUTPUT

The WLF combines two primary and two secondary shafts with a sizing screen. Oversized pieces remain in the chamber for repeated cutting, allowing a more controlled fraction than an unscreened primary shredder. Cutter arrangement, screen opening and drive selection are configured for the required material and throughput.
