The Eddy Current Separator
The Eddy Current Separator (ECS) is used to separate metallic and non-ferromagnetic materials from non-metallic ones. This magnetic separator of non-magnetic metals works on the principle of so-called eddy currents induced by a magnetic cylinder. A magnetic cylinder (separator rotor) with very strong neodymium magnets is embedded in the conveyor.
At high revolutions (when the magnetic poles alternate rapidly) it creates a magnetic field that magnetizes even non-ferromagnetic metallic materials for a short term. The magnetic polarity of the particles magnetized in this way is the same as the polarity of the magnetic field created by the separator rotor. Therefore, magnetized materials are repelled and automatically ejected out of the conveyor belt.
Description
Working Principle
Eddy current separation is based on the use of a magnetic rotor with alternating polarity, spinning rapidly inside a non-metallic drum driving by a conveyor belt.
Material is feed onto the conveyor belt of the eddy current separator, which moves it across the magnetic rotor where separation occurs.
As non-ferrous metals pass over the drum, the alternating magnetic field creates eddy current in the non-ferrous metal particles. The generation of eddy currents will cause a magnetic field inside the material, which repels the alternating magnetic field of the rotor, and repelling the material away form the the conveyor. While other materials drop off at the end of conveyor, the non-ferrous metals are propelled forward over a splitter for separation.
Range of Application
1. Mainly suitable for the industrial waste, living garbage sorting out in copper, aluminum and other non-ferrous metals, used to more fine separation.
2. Can be widely used in garbage disposal, automobile dismantling, recycling of waste electrical appliance and other fields, and processing industry of non-ferrous metal materials processing and other industries.
