Electromagnetic iron remover uses a high coercivity, high remanence special permanent magnets composed of composite magnetic system. With the advantages of maintenance-free, strong magnetic force, long life, simple installation, easy use and reliable operation, it is applicable to belt conveyors, vibration conveyors, electromagnetic vibrating feeders, and non-magnetic materials on chutes for removing iron. The electromagnetic iron remover uses high-strength permanent magnets made of neodymium iron and boron, which has high iron removal efficiency and long service life. The iron removal process is continuous and automatic, and no special care is required after the equipment is started. Suitable for closed powder conveying system, no dust escapes during work, no pollution to the environment. The iron removal function is continuously constant, and the iron arranging procedure is performed intermittently (time interval is adjustable), so the power consumption is low, and the mechanical system wear is extremely small. Compared with permanent magnetic iron remover, electromagnetic iron remover has deep magnetic force and strong permeation force. Popularly speaking, the rated suspension height is higher in the same type of magnetic field strength, and it is easy to remove iron. As long as the power supply is cut off, the ferromagnetic material is sucked. The objects are automatically unloaded, eliminating the need for manual removal of the permanent magnet remover, and the disadvantages of laborious and easy-to-harming human bodies.
