An '''Eddy Current Seperator'' is a conveyor system with a rapidly revolving magnetic rotor which generates an  induction field through magnet poles. The rotational speed generates a rapidly  changing magnetic field. In non-ferrous electrically conductive metal particles  (non-ferrous metals) a magnetic Eddy Current will be generated. Through this interplay of forces, the non-ferrous particle will be shot from the  product flow.

The number of magnetic poles and the  rotational will greatly affect the separation efficiency. There are magnetic rotors availible with 12 or 44 magnetic poles. The 12-pole rotors are used in coarse  fractions from 70 mm. The 44-pole  magnetic rotors are used in fine- or  medium fractions. The rotation speed plays  a major role. In fine fractions (0-20 mm), the machines can run 4000 rpm and be  effective in the separation of small  non-ferrous metal particles from about  2 mm.
