Working Principle:

In Magnetic Destoner separator, a short conveyor belt envelopes the magnetic roll and a tensioning ideal roll. A suitable feeder discharges materials on the belt. The ferromagnetic and paramagnetic particles adhere to the belt while the nonmagnetic particles flow freely off at the end of the conveyor.
