Working principle of eddy current separator
Eddy current separators remove nonferrous metals such as aluminum, die-cast metal, and copper from nonmetallic material.
When a piece of nonferrous metal, such as aluminum, passes over the separator, the magnets inside the shell rotate past the aluminum at high speed. This forms eddy currents in the aluminum, which in turn create a magnetic field around the piece of aluminum. The polarity of that magnetic field is the same as the rotating magnet, causing the aluminum to be repelled away from the magnet. This repulsion makes the trajectory of the aluminum greater than that of the nonmetallics, allowing the two material streams to be separated.
Application of eddy current separator
The eddy current sorting equipment is particularly suitable for the separation between high-conductivity and low-density substances and low-conductivity and high-density substances, and between conductors and non-conductors. Ferromagnetic substances cause high heat damage to equipment due to eddy currents. The processing objects of eddy current sorting are scrap copper (aluminum) power cables, aluminum products, automotive scrap, non-ferrous metal debris, printed circuit board gray ballast, non-ferrous metal-containing glass ballast, electronic waste, polymetal (Al, Cu , Pb, Zn) mixture, cast copper (aluminum) sand and ballast.
The main application industries of eddy current include: electronic waste recycling, municipal solid waste treatment, treatment of industrial solid waste, and purification of molding sand in aluminum and non-ferrous metal casting industry.
