The IPS 16B-1/4 is designed for industrial applications to reduce large volumes of paper, corrugated boxes, light metal foils, film, and plastics. This machine accepts any type of flat paper to be shredded from the lightest tissue to the heaviest corrugated. Safety features include an infeed guard, large hinged top cover to form over machine, switches to instantly shut down power motor when guards are removed, and control transformer automatically converts high voltage machine power to lower household current for maximum operator safety. As the compression roller flattens and reduces the material, the knife mill cutters tear into corrugated material, PET and PVC beverage containers and other bulk material forcing them in to the shredder feed opening. The heavy top conveyor exudes pressure to flatten the heaviest of cartons. Shredder materials are reduced to 1/4" strips at a rate of 2000 pounds per hour.
