Permanent Suspended Magnets

Permanent Suspended Magnets

Suspended permanent magnets is suitable for small models of conveyor belts or materials with thin thickness. It can couple with various of belt conveyors, vibration conveyors or chute to remove large pieces of iron from moving materials to purify materials and protect downstream equipment.

Suspended permanent magnets are heavy duty separators with a unique magnetic circuit design. It can provide a large magnetic force area and maximum magnetic field depth and is designed for removing iron over a moving bed of material. Basically, they are box-shaped units with permanent magnet material inside to produce a powerful magnetic field. To achieve maximum separation, it is important to optimally match the size of the block magnet (main pole) and the the speed of material conveyor belt.

Design principle

The suspended permanent magnetic separator is a strong magnetic field composed of a ferrite magnet with high coercive force and high remanence, or a ferrite + neodymium iron boron rare earth magnet. No power, no energy consumption.
