eddy current separator

Product Name: eddy current separator

Equipment composition: it is composed of sorter body and control cabinet. The main part consists of a selector assembly, a drive motor, a frame and a cover body. The sorting assembly is the core component of the equipment, which is composed of permanent magnet roller, material conveying system (including material conveying belt, belt driving roller and reducer motor).

Application of eddy current separator: it is mainly used for the separation of various non-ferrous metals such as copper, aluminum, etc. from the crushing chips of industrial solid wastes such as electronic wastes, waste plastic doors and windows, waste automobiles, etc.

Working principle of equipment: eddy current separation (ECS) is a separation technology using different conductivity of materials. Its separation principle is based on two important physical phenomena: an alternating magnetic field changing with time is always accompanied by an alternating electric field (electromagnetic induction law); A current carrying conductor produces a magnetic field (Biot Savart law). The principle of eddy current separation is as follows

When the equipment is working, a high frequency alternating strong magnetic field is generated on the surface of the sorting magnetic roller. When the conductive non-ferrous metals pass through the magnetic field, eddy current will be induced in the non-ferrous metals. The eddy current itself will produce a magnetic field opposite to the original magnetic field, and non-ferrous metals (such as copper, aluminum, etc.) will leap forward along their conveying direction due to the repulsive force of the magnetic field, To achieve the separation with other non-metallic substances, to achieve the purpose of separation.

The equipment is mainly distinguished by the ratio value of material conductivity and density. The material with high ratio value is easier to separate than the material with low ratio value.
