Conductive material sorting device

摘要

A conductive material sorting device includes a belt conveyer for supplying materials to be sorted, a roller wound with the belt conveyer, a magnet rotor inserted into the roller to be arranged at a portion of the roller wound with the belt conveyer and having a magnet arranged to alternate N and S poles with each other, and a drive device for rotationally driving the magnet rotor in the same direction as the roller and in the revere direction. An alternating magnetic field is generated by the rotation of the magnet rotor making it possible to send away conductive materials contained in the materials to be sorted along the most distant locus due to the repulsive force of a magnetic field caused by the eddy current generated in the conductive materials accompanying the generation of the alternating field.
