The disc-type electromagnetic iron remover has a large magnetic penetration depth, strong suction force, is dust-proof, rain-proof, and corrosion-resistant.

Working Principles ​
Inside the wound solenoid coil, a sorting tank filled with a certain amount of magnetically conductive stainless - steel wool (or steel plate mesh) is placed. After the coil is excited, the magnetically conductive stainless - steel wool is magnetized, generating a highly non - uniform magnetic field on its surface, that is, a high - gradient magnetized magnetic field. When the material passes through the steel wool in the sorting tank, paramagnetic materials are subjected to a magnetic field force proportional to the product of the applied magnetic field and the magnetic field gradient, and thus are adsorbed onto the surface of the steel wool. Non - magnetic materials, on the other hand, pass directly through the magnetic field and enter the non - magnetic product tank. When the weakly magnetic substances captured by the steel wool reach a certain level, ore feeding is stopped, the excitation power supply is disconnected, and the magnetic substances are flushed and made to flow into the magnetic product tank. Then, the next operation cycle begins.​

Application Fields​
Non - metallic Mineral Purification​
It is used for the purification and refinement of non - metallic minerals such as kaolin, bauxite, quartz sand, and feldspar. Fine weakly magnetic coloring impurity particles such as Fe₂O₃ and TiO₂ can be removed, improving the quality and whiteness of the ore.​

Metal Mineral Separation​
It is used for the beneficiation of weakly magnetic metal ores such as manganese ore, ilmenite, and rare - earth ore, increasing the ore grade and recovering useful minerals.​

Stable and Reliable Operation​
High - quality materials and advanced manufacturing processes are adopted. The mechanical structure of the equipment is robust and durable, and the electrical system is stable and reliable, featuring high anti - interference capabilities and a long service life.​
