During the transportation of materials on a belt conveyor, ferromagnetic impurities are often mixed in to ensure the safe and normal operation of machinery such as crushers and grinders in the conveyor system. This can also effectively prevent accidents where large or long iron objects might tear the conveyor belt and significantly improve the quality of raw materials. Magnetic separators are widely used in industries such as mining, ports, power plants, metallurgy, coal preparation plants, glass, cement, building materials, chemicals, and food, playing a significant role in ensuring the stable and safe operation of the conveyor system. Due to different application scenarios and magnetic circuit structures, various series of products have been developed.
