<p>PCT No. PCT/JP95/01338 Sec. 371 Date Dec. 11, 1996 Sec. 102(e) Date Dec. 11, 1996 PCT Filed Jul. 5, 1995 PCT Pub. No. WO96/01332 PCT Pub. Date Jan. 18, 1996A recycling method and apparatus that almost completely removes paints and pigments on the surfaces of empty aluminum cans to recover aluminum with very few impurities. Pressed blocks of aluminum cans are shredded into small aluminum pieces (a) by shredding means (1, 2, and 3), and foreign matter mixed in the aggregate of aluminum pieces obtained is removed. The aggregate of small aluminum pieces (a) free from foreign matter is agitated by a paint removing device (20) using a rotating body (36) that rotates at a high speed, in order to remove paints and pigments coated on the surfaces of the aluminum pieces (a) employing frictional force caused by the difference in speed as well as adhesion. The small aluminum pieces (a) free from paints and pigments are molded again into aluminum compacts (b) by a compression molding machine.</p> |
