They are crucial for protecting crushers, screens, and other machinery from damage due to ferrous materials.

Eddy Current Separators

While not strictly a magnetic separator, eddy current separators are often used in conjunction with them. Eddy current separators use non-ferrous metals. The eddy currents in the rotating magnetic field repel the non-ferrous metals and separate them from the rest of the material. This is particularly useful in recycling facilities. This technology allows for the recovery of valuable non-ferrous metals like aluminum and copper. The combination of magnetic and eddy current separators can provide comprehensive separation solutions. They are commonly used in the recycling of automotive shredder residue and the recovery of metals from electronic waste. The effectiveness of eddy current separators depends on the conductivity and size of the non-ferrous materials being separated.
