Eddy current separator is a solid waste sorting equipment based on the principle of electromagnetic induction, which is mainly used to efficiently separate non-ferrous metals from mixed materials. Its core working principle is to generate an alternating magnetic field through a high-speed rotating permanent magnetic roller or drum. When conductive metals (such as copper, aluminum, etc.) pass through the magnetic field, eddy currents will be induced inside the metal, and then an induced magnetic field in the opposite direction of the original magnetic field will be generated. According to Lenz's law, this magnetic field interaction will produce a repulsive force (Lorentz force), thereby ejecting and separating the conductive metal, and realizing the automatic sorting of non-ferrous metals and non-metallic materials (such as plastics, glass, etc.). The equipment has the characteristics of high sorting efficiency, low energy consumption, and high degree of automation. It is widely used in electronic waste treatment, automobile dismantling, industrial waste recycling and other fields. It is one of the key technical equipment for realizing resource recycling and environmental protection treatment.

Eddy current separator is suitable for a variety of solid waste containing non-ferrous metals. The following are its main applicable materials:
1. Electronic waste
Circuit board fragments: Recycling conductive metals such as copper foil and aluminum components
Scrap electrical appliances: Separating copper wire and aluminum shell from broken materials such as refrigerators and air conditioners
Wires and cables: Separating copper core, aluminum core and insulating materials
2. Industrial waste
Automobile dismantling materials: Recycling broken bridge aluminum and copper parts (such as radiators and wiring harnesses)
Construction waste: Separating aluminum window frames, copper pipes and other metals
Industrial slag: Extracting non-ferrous metal residues such as copper and zinc
3. Domestic solid waste
Waste plastic doors and windows: Separating aluminum frames and plastics
Glass bottle aluminum caps: Recycling aluminum in bottle caps
Urban domestic waste: Separating mixed metal packaging (such as aluminum cans)
4. Other special materials
Metal tailings: Recovering copper, aluminum, etc. from ore processing tailings
Metal mixtures: Separating non-ferrous alloys such as copper, aluminum and zinc
