Permanent Magnet Dry Roller Magnetic Separator

The high-field-strength roller magnetic separator, developed and manufactured by Weifang Guote Mining Equipment Co., Ltd., is a high-gradient, high-field-strength magnetic separation device that can effectively remove weakly magnetic impurities from granular or coarse powder materials. This equipment is widely used in the purification of weakly magnetic impurities in industries such as ceramics, glass, refractory materials, abrasives, chemicals, food, and pharmaceuticals, as well as for the dry pre-selection of weakly magnetic ores such as hematite, limonite, and manganese ore.

Its main components include: a channel steel frame, magnetic rollers and drive rollers, magnetic roller mechanism belts, other stages of magnetic roller mechanisms, permanent magnet drums, various stages of material distribution adjustment plates, vibrating feeders, feed hoppers, equipment housing, observation windows, lower dust removal port, upper dust removal port, and various stages of power and transmission systems.

Product advantages: Utilizing a multi-stage composite magnetic separation structure of permanent magnet drums and permanent magnet rollers, it can effectively separate most magnetic particles from materials. The permanent magnet drums employ a new type of compensated magnetic pole magnetic system with a flipping mechanism, achieving a magnetic field strength of up to 8000 Gauss, resulting in greater magnetic field strength, stronger attraction, and a higher removal rate. The magnetic roller employs a composite magnetic system with a magnetic field strength of up to 18,000 Gauss. The conveyor belt used in the magnetic roller mechanism is made of a special material, offering excellent wear resistance and a long service life. A vibrating feeder ensures uniform and quantitative feeding of materials into the magnetic separator, guaranteeing a consistent material layer thickness and maximizing the separator’s functionality to improve separation efficiency. The power and transmission system utilizes a renowned brand of variable frequency speed-regulating motor, allowing real-time adjustment of the permanent magnet drum and magnetic roller mechanism’s speed according to material conditions. This adapts to and meets the particle size and output requirements of various materials. Dust collection ports located at the top and bottom of the equipment can be connected to dust collection equipment. Dust generated during mineral processing is contained within the casing and expelled from the equipment through negative pressure generated by the dust collector fan for centralized treatment, ensuring no dust pollution occurs during mineral processing.

Working Process: Granular material falls through a feed hopper into a vibrating feeder and is evenly vibrated and fed to the working area of ​​the permanent magnet drum. Magnetic particles are firmly adsorbed to the drum’s surface and carried into a non-magnetic field zone, where they are discharged through the magnetic material outlet. Non-magnetic material, under the influence of gravity and inertia, falls onto the magnetic roller mechanism for the next stage of magnetic separation. A conveyor belt transports the material to the magnetic roller. In a magnetic field of up to 18,000 gauss, weakly magnetic particles are firmly adsorbed to the roller’s surface. The conveyor belt then carries the material to a non-magnetic field zone, where they are discharged through the magnetic material outlet. Non-magnetic material then enters the next stage of the magnetic roller mechanism. After multiple separations, non-magnetic particles are discharged through the non-magnetic material outlet at the front of the equipment.
