Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a high-energy ball mill for preparing rare earth permanent magnet powder. Background Art

[0002] Rare earth permanent magnet powder refers to alloy powder composed of rare earth elements and metal elements such as iron, cobalt, and nickel, which has excellent magnetic properties and high heat resistance. Rare earth permanent magnet powder is widely used in various fields, such as motors, generators, transformers, sensors, maglev trains, etc.

[0003] In the prior art, a ball mill refines raw materials by collision and grinding between balls and between balls and a tank body, so that the raw materials meet the particle size requirements for preparing rare earth permanent magnet powders. After preparation, the inside of the tank body of the ball mill needs to be cleaned. Due to the properties of the rare earth permanent magnet powders themselves, a mixed liquid of water, corundum media such as quartz sand, and detergents needs to be added to the tank body when cleaning the tank body, and then the ball mill is started for rotation and cleaning. However, the mixing of water, corundum media and detergents is often carried out in the tank body of the ball mill. When the tank body of the ball mill starts to rotate, the high-purity detergent and corundum media are likely to cause greater wear on the inner wall of the tank body, which will reduce the service life of the tank body of the ball mill in the long run.

[0004] Therefore, it is necessary to invent a high-energy ball mill for preparing rare earth permanent magnet powder. Utility Model Content
