Eddy Current Separator Operating Principles
The Eddy current separator starts with a short belt conveyor with a high speed magnetic rotor system installed at the discharge end and its drive located at the return end. The magnetic rotor is positioned within a separately rotating non-metallic drum. This magnetic rotor revolves at approximately 3000 rpm during operation. Meanwhile, the outer drum cover rotates at the same speed as the belt conveyor.
While the rotor spins at these exceptionally high speeds, it introduces an electric current into conducting metals. This electric current then produces a magnetic field, which goes on to oppose the field created by the rotor and repels conducting metals over a pre-positioned splitter plate. Any remaining materials will free-fall over the rotor, ensuring they are separated from the repelled metals.
