ABSTRACT:
A scrap recovery and feed system wherein scrap plastic is recovered from a plastic manufacturing process, such as in the manufacture of sheet, film, formed or molded objects, and the scrap plastic is chopped up and fed back to the processing machine along with the base material, such as a virgin plastic material and various additives. The scrap is fed with an auger from an upper hopper toward the outlet opening of a lower hopper containing the base material. The materials are mixed just prior to entry in the extruder or other processing machine.
