<P>PROBLEM TO BE SOLVED: To provide a sorting apparatus capable of preventing a magnetic material from adhering to a pulley or a rotating rotor during rotation drive, and a vicinity of the pulley from occurring overheating when sorting a magnetic metal, a non-magnetic metal and a nonmetal in a mixed recovery material. <P>SOLUTION: The sorting apparatus provided with magnetic metal, non-magnetic metal and nonmetal sorting means to sort and recover the magnetic metal by adsorbing with magnetic force, the non-magnetic metal by blowing off backward using repulsion due to an eddy current and the nonmetal using natural drop from a belt conveyor among materials to be sorted (magnetic metal, non-magnetic metal and nonmetal) conveyed backward on the belt conveyor includes: an air jetting device for jetting air on the circumference surface of the pulley on the rear end side as magnetically adhering prevention means to prevent impurities having magnetic properties intermixed on the belt conveyor together with the material to be sorted and floating in the air from magnetically adhering to the pulley and a rotating drum during rotation drive. <P>COPYRIGHT: (C)2013,JPO&INPIT |
