High alumina balls have characters of wear resistance and grinding resistance as a kind of good neutral refractory that we can use it in a right way according to its chemical nature.
High alumina ball is produced with high temperature alumina powder, which can be subdivided into four series of 90, 92, 95 and 99.
High alumina ball has two types of inactive and active. Active high alumina ball can be used to adsorb impurities and clean products. Inactive high alumina ball can be used to grind or as chemistry filler.
High alumina ceramic balls are mainly used in ceramic factory. The date shows that use natural ball stone and 10% content of grind sposh which can shorten the milling time about 15%, use medium-alumina ball and 30% high alumina ceramic balls to grind sposh comparing that grind with only medium-alumina ball which can shorten about 30% milling time.
