PURPOSE:To effectively sort conductive materials regardless of the kinds and sizes of the conductive materials by generating AC magnetic fields by the rotation of a magnetic rotor and making the conductive materials fly in the loci most distant therefrom by the repulsive force of the magnetic field by the eddy currents generated in the conductive materials in the materials to be sorted according to these magnetic fields. CONSTITUTION:This sorting device consists of a belt conveyor 1 which supplies the materials to be sorted, rollers 21, 22 around which this belt conveyor 1 is wound, the magnet rotor 3 which is inserted into the roller 21, is disposed in the part of the roller 21 wound with the belt conveyor 1 and is disposed alternately with N poles and S poles of the magnet and a driving device 40 which rotationally drives the magnet rotor 3 in the same direction as the direction of the roller 21 and the direction reverse therefrom. The alternating magnetic fields are generated by rotation of the magnet rotor 3 and the conductive materials are made to fly in the loci most distant therefrom by the repulsive force of the magnetic fields by the eddy currents generated in the conductive materials in the materials to be sorted accompanying the generation of these magnetic fields. |
