Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a permanent magnetic drum type magnetic separator with high ore dressing efficiency. Background Art

[0002] The magnetic separator is a screening device used to remove iron powder from recycled powdered particles. After the slurry flows into the trough through the feed box, the ore particles enter the feeding area of ​​the trough in a loose state under the action of the water flow in the feed water pipe. 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 slurry and move toward the magnetic poles and are adsorbed on the cylinder.

[0003] When the current magnetic separator is in use, the ore is usually poured directly into the magnetic separator. Since the ore contains materials of different sizes, if the larger materials are directly poured into the magnetic separator, the magnetic separation drum cannot guarantee the separation effect of the larger materials, which will affect the efficiency of mineral processing. For this reason, we propose a permanent magnet drum magnetic separator with high mineral processing efficiency to solve the above problem. Utility Model Content
