CONTINUOUS UNWANTED IRON SEPARATION
Another type of magnetic separator is the magnetic pulley. In this configuration the magnet is embedded in the head pulley of the conveyor. As the pulley spins, the magnetic force grabs the ferrous particles and carries them around and under the pulley until the natural belt separation from the face of the pulley forces the particles to fall in a separate bin. While suppliers are wary of recommending a pulley versus an overhead magnet unless they know the specific application, most say that, generally, a pulley will pull out finer particles of ferrous than an overhead magnet.
This better sort is possible because material is closer to the magnet, which is just under the belt. Also, the pulley has gravity working in its favor. This method, however, may not be effective in pulling off larger pieces of ferrous material or material that is trapped on top of the material stream.
Applications of Permanent Magnetic Pulley:
Installation on Mobile Crushers, Screens and Shredders
Separation of ferrous contamination in quarries
Removal of ferrous materials in mining operations
Separation of ferrous in municipal solid waste recovery
Removal of ferrous contamination in glass recycling
Separation of ferrous metals in skip waste recycling
Removal of ferrous from foundry applications
