PROBLEM TO BE SOLVED: To enable a device to surely perform the sorting recovery of conductive nonmagnetic metal pieces with small bores. SOLUTION: In this rotary drum type nonmagnetic metal sorting recovery device, and endless conveyor belt 10 is wound on a driving roller 9, a passive roller 11 and an auxiliary pulley 12, a cylindrical nonmagnetic drum 1 incorporating a permanent magnet rotor 4 freely rotatably arranged is provided by being brought in contact with the inner peripheral surface of the endless conveyor belt 10 and on the outer peripheral surface of the permanent magnet rotor 4, first magnets whose the magnetizing direction nearly coincides with the tangential direction and second magnets whose the magnetizing direction nearly coincides with the normal direction are alternately installed. The permanent magnet rotor 4 is rotated in the same direction as or reverse to the advancing direction of the conveyor belt 10 and conductive nonmagnetic metal 15 which is magnetically floated is separated and recovered by a sucking device. |
