Magnetic Head Pulley

Magnetic Head Pulley

The permanent 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.

Magnetic head pulleys, comprising of a shaft with the magnetic system built on it, are usually installed in belt conveyors. Both ends of the shaft are adapted according to clients needs. The magnetic system induces a strong magnetic field functioning all over the perimeter. All magnetizable material is attracted and pulled to the pulley, until it is extracted from the magnetic field by the lower run of the belt.

Design principle

The material flows on the conveyor belt that surrounds magnetic pulley surface. When the material is dropping, the ferromagnetic material is attracted by the magnetic force and its running trajectory is separated from the flat trajectory of the non-ferromagnetic material. Then their trajectory can be automatically separated.

Characteristics and advantages

  • High magnetic forces
  • No additional operating and energy cost, no maintenance
  • Integrated easily as pulley of a belt conveyor
  • Can be installed as an add-on addition
  • Prevent machinery from damage and product from contamination
  • Automatic iron removal without manual cleaning

Optional configuration

  • A variety of magnetic circuit and temperature tolerance criteria are available
  • Size and specification of magnetic pulley can be customized according to requirements
  • Ends of shaft made according to clients needs


Widely been used in belt conveyors for continuous automatic removal of damaging tramp iron from a variety of materials.

Material handling

Food, feed, recycling and waste, ceramic and glass raw materials, abrasives and refractory, wood chips, chemaicals, plastics, slag processing, etc.
