APPARATUS FOR CRUSHING RESIN WASTE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for crushing a resin waste material which is easily manufactured and can crush the resin waste material minutely and efficiently. SOLUTION: The surface of a rotary drum (100) is provided with a plurality of rhombic protrusions (101) formed by engraving a plurality of clockwise spiral grooves parallel to each other and a plurality of anticlockwise spiral grooves parallel to each other. The resin waste material is alternately pushed to the surface of the rotary drum and minutely crushed by two resin waste material pressing members (213) reciprocated by two cylinders (210). Cooling water is fed from one side of the shaft (110) of the rotary drum and discharged from the other side.
