How Eddy Current Separator Work:
In an eddy current separator, there is a short belt of conveyors that has its drive located at the return end and a high-speed magnetic rotor system installed at the discharge end. This rotor, which is positioned within a separately rotating non-metallic drum, revolves at high-speeds during working, whilst the outer drum cover rotates at the speed of the eddy currents belt conveyor.
While the rotor spins, electric current is induced into the conducting metals of the flow. This current creates a magnetic field, which opposes the field created by the rotor, repelling the conducting metals over a pre-positioned splitter plate, completing the separation process. The remaining materials such as plastics, glass, and other dry recyclables will simply free-fall over the rotor, separating them from the repelled metals.
