METHOD AND APPARATUS FOR USED ALUMINUM CAN RECYCLING

摘要

A method of and an apparatus for recycling aluminum having a very low content of impurities, after removing paint and pigment substantially completely from the surface of a used aluminum can. Pressed blocks of aluminum cans are crushed into small aluminum pieces a by crushing means (1, 2, 3), and the extraneous matter mixed in the aggregate of the crushed aluminum pieces a is removed. The resulting aggregate of small aluminum pieces a is agitated in a paint removing unit (20) utilizing a rotary body (36) which is adapted to be rotated at a high speed to remove the paint and pigment from the surfaces of the small aluminum pieces a by a frictional force and adhesive force occurring due to a speed difference. The small aluminum pieces a from which the paint and pigment have been removed are formed into molded aluminum bodies b on a compression molding machine (40).
