[0002] A magnetic separator is a screening device used to remove iron powder and the like from recycled powdery granules. After the ore pulp flows into the trough through the feed box, under the action of the water flow of the feed water spray pipe, the ore particles enter the feed area of the trough in a loose state. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form magnetic clusters or magnetic chains. The magnetic clusters or magnetic chains are affected by the magnetic force in the ore pulp and move towards the magnetic pole and are adsorbed on the cylinder.

[0003] When the existing magnetic separator is used for magnetic separation of fine iron powder, dust is likely to cause dust flying, which is likely to cause harm to the environment and affect the normal operation of the magnetic separation equipment at the same time; and during the magnetic separation process, with a large amount of dust mixed with fine iron powder entering the magnetic separator, it is easy for the dust to cover some fine iron powder, resulting in waste of some fine iron powder with the discard of the dust, which is not conducive to the full magnetic separation and use of fine iron powder.
