eddy current separation

Eddy current separator - Wikipedia

An eddy current separator uses a powerful magnetic field to separate non-ferrous metals from waste after all ferrous metals have been removed previously by some arrangement of magnets. The device makes use of eddy currents to effect the separation. Eddy current separators are not designed to sort ferrous metals which become hot inside the eddy current field. This can lead to damage of the eddy current separator unit belt.

Eddy Current Separation - an overview ScienceDirect Topics

Eddy current separation takes advantage of the large range in conductivities of many of the mixed metals present in co-mingled automotive (and other) scraps (Table 1). Eddy current separation is a similar concept to magnetic separation. A rotor is lined

Eddy Current Separator For Non-Ferrous Metal MSW Separation

This eddy current reacts with different metals based on the conductivity-to-density ratio, creating a repelling force on the charged particle. Light and a conductive metal, such as aluminum, can easily rise and thus be ejected from the normal flow of the product stream making separation possible. Eddy current separators have been extremely ...

Eddy Current Separator - 911Metallurgist

The principle of eddy current separation is that an electric charge is induced in a conductor by changes in magnetic flux cutting through it. Such changes in magnetic flux can be achieved by using a rotating permanent magnet, and magnetic flux intensity can be controlled by using an electrical conductor.

Eddy Current Separator - Bunting Europe

Eddy Current separation combines the use of a magnetic rotor, with alternating polarity, spinning quickly inside a. non-conductive drum which is driven by a conveyor belt. The external drum operates as the head pulley and rotates at belt speed. The internal rotor moves at a higher speed than the drum which creates a strong repelling force through

Aug 12, 2001  All eddy current machines have a specified working width. The strength of the magnetic flux (the eddy currents) is consistent across this width. Use it all – even when feeding the eddy current below its rated capacity, if the material is not distributed evenly across the working width, effective separation will not be achieved.
