Key Property

• Alumina balls are made from good quality and high temperature alumina powder with the characters of high degree purity, high intensity, high hardness, more white and less wear abrasion and no effect for the grinded materials.
• Alumina ball is isostatic pressed with high density, it can increase grinding efficiency, reduce grinding time and increase effective volume of grinding mill, thereby increasing the amount of grinding material.
• Alumina ball have very lower wear resistance can prolong the service life of grinding medium
• It also have the properties of high temperature resistant, acid and alkali resistant, corrosion resistant.

Application Filed

• Mainly used in ceramic, porcelain glaze, glass, chemical industry. It is the grinding medium for ball mill, pot mill, vibration mill and other fine powder grinding equipment, its grinding and wear resistance efficiency is much better than the normal ceramic ball and nature stone.
• It also can be used for polishing of metal and grinding for nonmetal minerals powder(such as zirconium silicate powder, kaolin etc.)it can be used in all type of grinding and polishing machine.
