How does a magnetic drum separator work?

drum magnet removes metal from powder

A magnetic drum separator removes ferrous metal from dry, free-flowing bulk solids. It is self-cleaning and available within a housing or as the magnetic drum only.

How does a magnetic drum separator work?

A uniform product flow is introduced to the magnetic drum separator using a vibratory feeder or conveyor.  The material enters the top of the housing and flows across the surface of the drum. As the drum shell rotates around the stationary magnetic field, all non-ferrous material, which is unaffected by the magnet, falls free from the magnet into the “cleaned” flow. All ferrous tramp metal is captured by the magnetic field and is held onto the drum’s surface. As the drum rotates, the metal is carried past the diverter and released outside of the magnetic field for collection and disposal.
