The IPS 20 Combo is a heavy-duty combination knife mill disintegrator with a conveyor and hopper design. It comes equipped with both a 3 horsepower and 7.5 horsepower motor, working together to shred larger volumes of material. It offers efficient service for destroying paper, plastic, corrugated boxes, wire, metal and newspapers and is capable of cutting up to 90 feet per minute for fast shredding operations. The shred size is granular; so small it can't even be measured. A pinch style conveyor system compresses corrugated material, PET and PVC beverage containers. The material is then force fed into the shredder where it is reduced to particles. The hopper feed allows materials to be dumped into the top and compacted for waste destruction. Waste volume is limited only by shred bag or output hopper size. Optional spare knives and filtering screens are available.
