Ceramic grinding balls are a kind of non-metallic grinding media that is widely used in industrial grinding. There are many physical and chemical advantages that are different from metal grinding balls. Today I will introduce you to his characteristics and applications. Ceramic grinding balls are made of high-purity alumina powder after isostatic pressing and high-temperature sintering. The density of 92 alumina balls is about 3.6, the Mohs hardness is 9, the water absorption is close to 0, and the self-wear is 0.01%.
Glass grinding, first of all, the hardness of the glass is very high. The ordinary grinding media has limited processing ability. The mixing of too many impurities will greatly reduce the quality of the glass, resulting in a poor quality of the finished glass and the inability to make high-quality products. The alumina grinding ball can solve this problem. Quartz grinding, the hardness of the same quartz is also very high, especially high white quartz has high requirements for whiteness, and the color of aluminum oxide is white, which solves the grinding problem of high white quartz from many aspects.
