Eddy current separation is a developed technology with many practical applications in the recycling industry. The basic principle is derived from the fact that when a permanent magnet passes over a conductive metal object, electric charges within the metal tend to experience a net magnetic force . This causes distinct swirling flow patterns of ...

A new eddy current separation motion model is established, and the effects of the shape coefficient and air resistance on the separation trajectory of battery materials are quantified. Theoretical and experimental results show that metal fragments suitable for carrying eddy currents are attainable by treating electrode plates with a 20 …
Eddy current separation (ECS) is an environment-friendly technology for separating nonferrous metallic particles whose size was from 2 mm to 10 mm. No wastes are generated in ECS. ECS quality of nonferrous metals from solid wastes is rather low in the production practice of spent lithium iron phosph …
The eddy currents (also called Foucault's currents) are generated by the machine's magnetic rotor. An Eddy Current Separator mechanically resembles a conveyor belt and it is usually installed in line in a waste recycling plant. The main purpose of the machine is to separate the Non-ferrous metals from non-metals or, eventually, recover fine ...
The eddy current separation method usually sorts this non-ferrous scrap. Eddy current separation takes the principles of electromagnetic induction in conducting materials, to separate non-ferrous metals by their different electric conductivities. The main principle is that ' an electrical charge is induced into a conductor by changes in ...
