The IPS 20B-1/4 reduces large volumes of paper, magazines, corrugated boxes, foils, film, and plastics into 1/4" strips. Entire wastebaskets full of material can easily be dumped onto the conveyor system for destruction. The compression roller automatically flattens cartons, boxes, and other bulky material preparing it to be fed into the shredder opening. A "reel type" cutting cylinder works like a windmill tearing into corrugated material, PET and PVC beverage container force-feeding them into the shredder. The knife mill disintegrator tears in to 300 sheets per pass. The 10 horsepower motor works hard to shred up to 4,000 pounds of material, working up heat pressure that is automatically cooled by the totally enclosed, overload-protected, motor fans. Container to catch shredded material not included.
