Keywords: mill ball with a high content of alumina, 92% Al2O3, mill ball, grinding balls
Grinding balls or aluminum oxide grinding balls are widely used in ball mills as an abrasive medium for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glass factories due to extremely high density, high hardness, high wear resistance.
During abrasive/grinding processes, ceramic balls will not break and will not contaminate the grinding materials.
Application:
1)aluminum oxide grinding balls are one of the ideal grinding media for mills, can keep the purity and improve the stability of the prepared materials.
2) aluminum oxide grinding balls are widely used in ball mills as an abrasive medium for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glass factories.
3) the main characteristics are high density, high hardness and strength, high wear resistance, heat resistance, corrosion resistance and no pollution, etc.
4) during abrasive/grinding processes, ceramic balls will not break, they will not contaminate the prepared materials.
5) type: depends on the aluminum oxide content: 60-70%, 65-75%, 95%.
Advantages
(1) High wear resistance
The wear resistance of aluminum oxide balls is higher than that of ordinary balls. The working balls do not pollute the grinding materials, so it is possible to keep clean and improve the stability of the prepared materials, especially ceramic glaze.
(2) High density.
High density, hardness and excellent grinding characteristics will save grinding time, increase the crushing space. So it can improve the grinding efficiency.
