Why is the large-scale application of the suspended permanent magnet separator limited

The suspended permanent magnet iron remover is equipped with an automatic iron unloading device on the basis of the conventional permanent magnet iron remover, and the suspended permanent magnet iron remover is unloaded by the conveyor belt of the iron unloading device, and the suspended permanent magnet iron remover is made of high coercivity. The high magnetic remanence rare earth magnetic material, the magnetic source composed of neodymium iron boron and ferrite, forms a strong magnetic field, which is used to remove the ferromagnetic impurities in the material, and the whole machine does not need to be connected to electricity, and energy consumption is not formed. Common suspended permanent magnet separators include automatic iron remover and manual iron remover.
The suspended permanent magnet iron remover can automatically unload iron, has the characteristics of constant magnetic field, constant hot and cold state, and few failure points. It is relatively common in applications with bandwidths below 1200 mm. However, due to the development of magnetic shielding technology, the manufacture, transportation, installation, operation and maintenance of the equipment have brought certain troubles. For example, if a large piece of iron is sucked onto the magnetic box, there may be a problem that it may not be discarded and may cause the motor to burn out. At the same time, it is not easy to disassemble and may cause damage to the magnetic block, and therefore, there are certain limitations in large-scale applications.
