The wear resistance of alumina grinding balls is higher than that of ordinary alumina balls, and it is suitable for grinding media used in ball mills. It does not contaminate the abrasive material when working, so it can maintain the purity and improve the stability of the abrasive material, especially the ceramic glaze. Alumina grinding balls have high density, high hardness and high grinding characteristics, which saves grinding time and expands the grinding space, which can improve grinding efficiency, making it widely used in ceramic raw materials in ceramic factories, cement factories, enamel factories and glass factories. and glaze in a ball mill.

.High wear-resistance:
The alumina balls' wear-resistance is higher than the common alumina balls'. When it is working, the ball won't pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
.High density
High density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
1.Grinding ceramic ball is one ideal ball mill grinding media, it can keep the purity and improve the stability of grinded materials.
2.The alumina grinding ball have been widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glasswork.
3.The main features are high density, high hardness and strength, high wear resistance, thermal stability, corrosion resistance and non-pollution etc.
4.During the abrasive/grinding processes, ceramic balls will not be broken, it will not contaminate the materials to be grinded.
5.Type: According to the content of aluminum oxide: 60-70%, 65-75%, 95%.
