Aggregate and Mining Products – Suspended Permanent Magnets, TIANLI brand suspended permanent magnets are used in many of the same applications as the suspended electromagnets. Except in the instances of very fast belts or deep burden, a permanent magnet can successfully remove tramp metal from a conveyor belt product stream. Usually, the removal of the tramp metal can be obtained for a lower cost than an electromagnet. TIANLI brand suspended magnets are ruggedly built for demanding, rough service applications. Permanent magnets are available as manual cleaning or automatically cleaning magnets. Manual cleaning is generally done by an arm that is manually rotated across the face of the magnet, but many other options are available. The automatically cleaning version is built with a heavy duty rubber belt to continuously remove tramp metal from the face of the magnet. Permanent magnets are available in standard ceramic, hi-power ceramic or rare earth.
