Eddy current separator
Machine that separates non-ferrous metals from an input stream
An eddy current separator (ECS) is a machine that uses a powerful magnetic field to separate non-ferrous metals from an input waste or ore stream. The device makes use of eddy currents to effect the separation. Non-ferrous metals typically separated by an ECS include aluminum, copper and die-cast metals.[1]
In waste processing, ECS is used after all ferrous metals have been removed previously by some arrangement of magnets. Eddy current separators are typically used at the end of the waste material stream, since ferrous metals will become heated when exposed to an eddy current field, leading to potential damage to the eddy current separator.[2]
In mining, ECS is sometimes used to separate metals from mined ore.[3]
