Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a magnetic cylinder for a magnetic separator with a filtering structure. Background Art

[0002] Magnetic separator is a screening device used to remove iron powder from recycled powder particles. After the slurry flows into the tank through the feed box, the ore particles enter the feeding area of ​​the tank in a loose state under the action of the water flow of the feed water pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically gathered to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the slurry and move toward the magnetic poles and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the "magnetic clusters" or "magnetic chains" produce magnetic stirring due to the alternation of magnetic poles when the "magnetic clusters" or "magnetic chains" rotate with the cylinder. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic lotuses" that are finally adsorbed on the surface of the cylinder are the concentrates.
