Alumina grinding ball is one ideal mill grinding media, it can keep the purity and improve the stability of the grinded materials especially the ceramic glaze. High alumina ceramic balls as grinding ball with high quality raw materials as well as the middle alumina ceramic balls are produced with the following technology: advanced spray drying technology, dry type full automatic isostatic pressure and high temperature roller kiln sintering technology.
Mid-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 65%-70% alumina content as medium-aluminum balls. Some types mainly made by hand by some special ceramic factories.
Application:
Grinding Balls are suitable for grinding medium used in ball grinding machines.
