An [[Eddy Current Separator]] (ECS) is a machine that is used to separate and recover [[Non-Ferrous Metal|non-ferrous metals]] such as aluminium, copper and brass from non-metallic material in a [[Waste|waste]] stream<ref name="ref1" />. Material is fed onto the conveyor of the separator, which moves it across the magnetic rotor, situated underneath, to result in separation. The two resultant streams discharge into different bins/compartments with the aid of the splitter which divides the [[Non-Ferrous Metal|non-ferrous metal]] from the non-metallic [[Waste|waste]] such as [[Paper|paper]], [[Plastic|plastic]], [[Wood|wood]] or [[Automotive Shredder Residue|automotive shredder residue]] (known as shredder [[Fluff|fluff]])<ref name="ref2">[https://www.recyclingtoday.com/article/magnetic-equipment-guide----eddy-current-separators/ Magnetic Equipment Guide - Eddy Current Separators]</ref>. This process is usually employed after magnetic separation has removed the bulk ferrous fraction from a scrap material stream<ref name="ref3">[https://www.sciencedirect.com/science/article/pii/S089268751830582X Eddy Current Separation]</ref>. | |||

The key component is the magnetic rotor, which is a series of permanent rare earth magnets mounted on a support plate attached to a shaft. The magnetic rotor is surrounded by, but not attached to, a non-metallic shell which supports the conveyor belt. This allows the rotor to spin independently and at a much higher speed than the non-metallic shell and belt<ref name="ref2" />. | The key component is the magnetic rotor, which is a series of permanent rare earth magnets mounted on a support plate attached to a shaft.
