Performance and Application of 92 Alumina Grinding Ball

Alumina grinding balls refer to materials such as bauxite, roller powder, industrial alumina powder, and high-temperature calcined Alpha alumina powder as raw materials, which are produced through batching, grinding, powder milling, molding, drying, firing and other processes. It is a ball stone widely used mainly as a grinding medium.

According to different specifications, there are different types of alumina grinding balls. Among them, the specific gravity of 92 alumina balls is above 3.60, the alumina content is above 92%, and the iron content is low. The same raw material, the same formula, and the same firing temperature, the smaller the fineness of the powder after the raw material is ground, the higher the specific gravity and the better the wear resistance.

Because of its high strength, high hardness, high wear resistance, high specificity, small size, high temperature resistance, corrosion resistance, pollution-free and other excellent characteristics, it is widely used in different types of ceramics, enamel, glass, chemical and other factories. The fine processing and deep processing of thick and hard materials is the grinding body of ball mills, pot mills, vibration mills and other fine grinding equipment. Its grinding efficiency and wear resistance are much better than ordinary ball stones or natural pebbles. Compared with natural stone balls and ordinary porcelain balls, the wear resistance of 92 alumina balls is increased by 20-40 times, the grinding efficiency is increased by 40-60%, and the mill effective efficiency is increased by 30-40%. The overall cost is natural stone balls. 40-60% of the mill’s life, the life span of the mill is increased from 2 years to 6-8 years.
