摘要： PURPOSE:To almost completely remove the coating materials of can surfaces and regenerate Al free from impurities by cutting the empty Al cans to fine pieces and removing foreign matter, then agitating the assembly thereof by a high speed rotation to peel away the foreign matter on the surfaces of the fine Al pieces. CONSTITUTION:The empty Al cans of containers for potable biverage water, etc., are successively treated by crushing machines 1 to 3 having crushing shafts 5, 11, 12, sieving machines 7, 13 and separators 6, 14. The empty cans are cut into the fine pieces of =4tons/cm by a compression molding machine 40, by which moldings b are obtd.

摘要： PURPOSE:To utilize aluminum can scrap at a high yield for a deoxidizing agent, etc., for making robust steel having a high sp.gr. by crushing the aluminum can scrap to fragments of specific grain sizes and annealing these fragments at a temp. below the m.p. to remove combustible foreign matter, then press forming the fragments at a high temp. CONSTITUTION:The pressed blocks of the aluminum can scrap are carried by means of a conveyor 4 into primary to ternary crushing machines 1, 6, 9 by which the pressed blocks are disintegrated and crushed to the fragments of about =4ton/cm , by which molded goods 17 are obtd.

摘要： PROBLEM TO BE SOLVED: To provide a sorting apparatus and method capable of perfectly sorting and removing substances to be sorted, for example, aluminium chips and other foreign matter from a material to be sorted, for example, an raw material to be sorted, which is obtained by coarsely crushing aluminium empty cans by utilizing specific gravity difference to make it possible to repeatedly recycle the raw material to be sorted, for example, aluminum empty cans, a punching vibration plate used in the sorting apparatus and an apparatus and method for regenerating an aluminum can utilizing the sorting apparatus. SOLUTION: A sorting moving floor is obliquely attached on the base frame disposed on a base stand and air sent by the blowing means arranged under the sorting moving floor is blown up to the surface of the sorting moving floor and a raw material to be sorted is charged on the surface of the sorting moving floor and foregin matter high in specific gravity is separated and moved toward the upper end of the moving floor while a substance to be sorted low in specific gravity is separated and moved toward the lower end thereof to sort the substance to be sorted and foreign matter other than the substance to be sorted. In this case, a punching vibration plate having a large number of vent holes 58a fitted thereto is used in the sorting moving floor 58.

摘要： PROBLEM TO BE SOLVED: To obtain a reproducing method for reproducing aluminum which almost perfectly removes coating and pigment on the surface of aluminum waste can while preventing the explosion of powdery dust and has extremely little impurity, and a device therefor. SOLUTION: A press block of the aluminum can is crushed into aluminum fine pieces with crushing means 1, 2, 3 and foreign matters mixed in an aggregate of the aluminum fine pieces are removed, and after removing the foreign matters, the aggregate of the aluminum fine pieces is heated at heating temp. of m.p. or lower to burn the combustible foreign matters. Thereafter, this aggregate is fed to a coating removing device 20a utilizing a rotary body rotated at high speed and stirred by rotating the coating removing device at the high speed under atmosphere having
