Eddy Current Separators

Eddy Current Separator Systems The Eddy Current Separator ( ECS) is an advanced metal sorting unit that is capable of separating non-ferrous metals such as aluminium and copper from domestic and industrial waste. Non-ferrous separators are very common in the fast growing market of can sorting, where they can provide an accurate separation of aluminium cans from dry recyclables. Dependent on the application there are two types of ECS rotors available, there is a high strength rotor for delicate or specialised separations, and a standard rotor for less complex separations such as aluminium cans.

Operating Principles An Eddy Current Separator consists of a short belt conveyor that has its drive located at the return end and a high speed magnetic rotor system installed at the discharge end. The magnetic rotor, which is positioned within a separately rotating non-metallic drum, revolves at around 3000 revolutions per minute during operation whilst the outer drum cover rotates at the speed of the Eddy Currents' belt conveyor. As the rotor spins at these high speeds, an electric current is induced into conducting metals. The induced electric current produces a magnetic field, which opposes the field created by the rotor, repelling the conducting metals over a pre-positioned splitter plate. The remaining materials such as plastics, glass and other dry recyclables will simply free fall over the rotor, separating them from the repelled metals.
