Application of Alumina Grinding Balls
Alumina grinding ball is a non-metallic grinding medium widely used in industrial grinding. It has many physicochemical advantages over metal grinding balls.
It is made of high-purity alumina powder sintered by isostatic pressing at high temperature. The density of 92 alumina ball is about 3.6, the Mohs hardness is 9, the water absorption rate is close to 0, and the self-wear rate is 0.01%. In view of the above characteristics, alumina grinding balls are widely used in fine grinding in various industries, and they are listed as follows:
Glass grinding, first of all, the hardness of glass is very high, and the processing capacity of ordinary grinding media is limited. Too much impurities will greatly reduce the quality of glass, resulting in poor quality of finished glass, and it is impossible to make high-quality products. Alumina grinding balls can solve this problem very well.
High white quartz is also very hard, especially high white quartz. The color of alumina is white, which solves the problem of grinding high white quartz from many aspects.
Lithium battery grinding is an emerging sunrise industry. Alumina grinding ball can show great power through its own material. We know that lithium battery materials are very sensitive to iron, so they cannot be ground with metal. Non-metallic grinding media, alumina grinding balls have high efficiency and good effect.
