Introduction:
High 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. 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.
Application:
Grinding Balls are suitable for grinding medium used in ball grinding machines.
