Eddy current separation devices are an effective way of removing non-ferrous metals from other products. Application such as aluminum cans from municipal waste, aluminum flakes from shredded PET, brass and aluminum from foundry sands and metals from shredded automobile scrap, other metals such as lead can also be removed. For successful non-ferrous separation, a magnetic should be installed prior to an Eddy Current Separator.

Eddy Current Separator is designed according to the principal that conductor can generate induced current in the high frequency alternating magnetic field.

A strong high-frequent magnetic alternating magnetic field generate on the surface of the sorting roller when it works ,then when conductive non-ferrous metal pass through the magnetic field, eddy current will be induced in the body of non-ferrous metals.

The eddy current itself will generate the opposite direction magnetic field ,non-ferrous metals(such as aluminum, copper etc.) will leap forward along its transport direction by the performance of magnetic field repulsion son as to separate other non metallic substances and achieve the purpose of sorting .

The main distinguishing criterion is material conductivity and density ratio values, a high percentage of the value of the material more easily to separated than the lower material.
