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 uniform feeding. Background Art

[0002] Magnetic separator is a screening device used to remove iron powder from recycled powdered particles. It is widely used in resource recovery, wood industry, mining industry, kiln industry, chemical industry, food industry and other factories. It is suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with a particle size of less than 3mm. It is also used for iron removal of coal, non-metallic minerals, building materials and other materials. It is one of the most widely used and versatile machines in the industry.

[0003] When the current magnetic separator is in use, the workers usually pour the ore directly into the ore box, and then the ore will continuously fall from the ore box into the magnetic separator. Since the ore continues to fall into the magnetic separator, the ore is likely to accumulate inside the magnetic separator, which will cause the ore after magnetic separation to be mixed with the ore that has not been magnetically separated, thereby affecting the effect of magnetic separation of the ore. For this reason, we propose a permanent magnetic drum magnetic separator with uniform feeding to solve the above problem. Utility Model Content
