It is used in various ceramic and vitrified tiles factories. The alumina balls are filled in ball mills over a fixed interval duration. The raw materials powder is mixed with the help of water in ball mills. The alumina balls crush the powder into a fine slurry while rotating in the ball mill. The ball mill mixing time is around 6 to 8 hr.
