Eddy Current Separation is based on the use of a magnetic rotor with alternating polarity, spinning rapidly inside a non-metallic drum driven by a conveyor belt. As non-ferrous metals pass over the drum, the alternating magnetic field creates eddy currents in the non-ferrous metal particles repelling the material away from the conveyor.
