Abstract

PURPOSE:To execute grinding for a short time by arranging passage for pushing out molding sand at lower part of a hopper for charging the molding sand, setting a rotary grinder at front part, installing a molding sand tank for recycle at upper part, communicating reducing/pressurizing transported tube from lower part to upper part and repeating transportation. CONSTITUTION:The large lump molding sand charged into a hopper 1 is pushed out with push-out member 2 from the passage 6 for pushing out molding sand and brought into contact with the face of the rotary grinder 3 under pressurizing and crushed. Iron pieces and core metal are collected into a cabinet 8 for impurities and wastes and only the molding sand, which becomes granule, is separated with a sieving member 13 on the carrying passage 12. It is carried to the reducing/pressurizing transported tube 10 collected in the upper space (a) in the molding sand tank 5 for recycle by sucking with a fan 11 for blowing up and a dust collector and piled up on a partitioned plate. By horizontally shifting the partitioned plate, the molding sand is dropped to an upper space a' and abutted on the face of the rotary grinder 3, to repeat the above process till obtaining the prescribed grinding degree.
