Alumina Grinding Ball

1)Alumina 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%, 95%
