Electro Magnetic Drums

Electro Magnetic Drums

The electric magnetic pulley is used to effectively sort large pieces of magnets and fine ferromagnetic particles from non-magnetic materials, maximally protecting downstream equipment from damage and realizing automatically iron removal.

Electric magnetic drum separators are used to separate tramp iron from bulk material of all kind. Bulk material is fed via a chute or vibrating feeder to the separator and is conveyed by the rotation of the drum casing. Magnetic particles are attracted by the internal permanent magnet, whereas nonmagnetic particles follow their flight path determined by inertia and gravity. The attracted material is conveyed by the drum shell to the end of the magnetic field and dropped to the other side of an adjustable splitter.

Design principle

As material reaches the drum, the magnetic field attracts and holds ferrous particles firml to the drum shell. Whereas the non-magnetic material is thrown forward by gravity and inertia, thereby achieving the automatic separation of ferromagnetic and non-ferromagnetic materials.

Characteristics and advantages

  • High magnetic forces
  • High availability
  • Rotary drum shell and adjustable magnetic filed angle ensure a best separation effect
  • Prevent machinery damage, prevent product contamination
  • Automatic iron removal is suitable for automatic production line

Optional configuration

  • Optimized solutions with radial or axial oriented magnetic fields
  • Multiple designs, tailor-made to the application
  • Ends of shaft made according to clients needs


Continuously and automatically separate magnetic impurities or ferromagnetic materials from a variety of materials. Improve product purity and protect downstream equipment.
