alumina balls, which are widely used in superfine mill to grind the kaolin clay, heavy calcium carbonate, steatite and so on into super fine powder. They have strong resistance to high temperature and pressure, lower ratio of the moisture absorbing, more stable chemical properties, capable of enduring the corrosion of acid, alkali, and organic solvent
