Aluminum oxide grinding balls have high hardness and wear resistance, which can maintain the grinding effect for a long time and reduce the wear and replacement frequency.

The purity is usually above 92%, even up to 99%, which ensures that no impurities will be introduced during the grinding process, keeping the material pure.

Aluminum oxide grinding balls have high density, which helps to improve the grinding efficiency and effect.

Low water absorption will not affect the humidity and formulation of the material, ensuring the stability of the material after grinding.

It has good resistance to acid, alkali and other chemicals, and will not have chemical reaction with the material to be ground during the grinding process.
