1. According to different sources of magnetic field, it can be divided into permanent magnet iron remover and electromagnetic iron remover.

2. according to the user's different requirements can be divided into purification type magnetic separator and protection type magnetic separator, the first type magnetic separator is mainly used for potassium sodium feldspar, quartz sand, kaolin and other non-metallic materials and food industry iron removal operations, to improve the quality of products; Protection type magnetic separator is mainly used in coal, port, building materials, chemical and other industries in addition to iron, is mainly used to relieving, anchor, lining board and other large metal objects separated from the material, in order to achieve the purpose of protection crusher, sieve, conveyor, at the bottom of front iron can reduce boiler furnace smelting furnace, prevent furnace bottom high, influence the use effect of boiler;

3. According to different ways of iron abandoning, iron abandoning can be divided into manual iron abandoning, iron abandoning after power failure and automatic iron abandoning;

4. According to the cooling mode, it can be divided into self-cooling iron remover, air-cooling iron remover, oil cooling iron remover, forced oil circulation cooling iron remover and superconducting iron remover;

5. According to the magnetic field strength, it can be divided into ordinary iron remover, strong magnetic separator and super strong magnetic separator. Of course, some manufacturers produce some non-standard iron remover in order to reduce the cost, and the magnetic field strength varies from 1500gs to 18000gs.
