DEVICE FOR GRINDING DOMESTIC AND INDUSTRIAL PLASTIC WASTES

摘要

FIELD: grinding domestic and industrial plastic wastes. SUBSTANCE: proposed device has cylindrical housing with perforated walls and crushing units whose working surfaces are provided with welded-on wear-resistant alloy; they are made in form of hammers and strikers; hammers mounted immovably on electric motor shaft are provided with longitudinal slots at their ends; strikers are mounted immovably on inner surfaces of perforated walls of housing in staggered order in two rows at spread of 30 deg. over circle , thus making strikers enter slots of revolving hammers; working surface of strikers have form of parabola. EFFECT: enhanced efficiency; increased productivity. 5 dwg
