Eddy current separator

The eddy current separator is applied to a conveyor belt carrying a layer of mixed waste. At the end of the conveyor belt is an eddy current rotor. Non-ferrous metals caught in the eddy current end up in a product bin, while other material falls off the belt due to gravity. Eddy current separators may use a rotating drum with permanent magnets, or may use an electromagnet depending on the type of separator. ==History==

for a device using eddy currents to separate non-ferrous metals from non-metals was granted to William Benson and Thomas Falconer of Eriez Magnetics in 1969. ==References==
