Product Description

 

Product Description

Grinding Balls are suitable for grinding medium used in ball grinding machines.

Alumina grinding balls refer to materials such as bauxite, roller powder, industrial alumina powder, and high-temperature calcined Alpha alumina powder as raw materials, after batching, grinding, milling (pulping, mud making), forming, and drying , Sintering and other processes, mainly used as a grinding medium and widely used ball stone. According to different alumina content, it can be divided into medium-aluminum balls, medium-high aluminum balls and high-aluminum balls. Generally, we classify those with 60%-65% alumina content as medium-aluminum balls, and those with 75%-80% alumina content are called medium-aluminum balls. Medium and high alumina balls, with more than 90% alumina content are high alumina balls. Among them, the high-alumina balls are subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain. Due to its extremely high production cost, few large-scale manufacturers manufacture 99 porcelain in large quantities. At present, it is mainly made by hand by some special ceramic factories.
