Operating principle

Operating principle The material mixture to be separated is fed to a rotating metal drum by a vibration feeder and then transported to the area of a corona electrode.


There it is electrostatically charged in a high-voltage field.


Conductive products (metals) lose their charge very quickly and are thrown off the rotary drum.


In contrast the non-conductors lose their charge very slowly.

They stick to the surface of the metal drum and are brushed off.

Thus a dry separation of both fractions is possible.

According to the principle of the loading, such separators are called "Korona drum separators" - KWS.



To achieve an optimal separation result, the materials must be constituted as follows:
