Introduction:
1)Grinding ceramic ball is one ideal ball mill grinding media, it can keep the purity and improve the stability of grind-ed 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 glass-work.
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 grind-ed.
5)Type: According to the content of aluminum oxide: 60-70%, 65-75%, 95%, 99%.
