Product Introduction
Alumina ceramic beads, due to their high alumina content, high density, high hardness and high wear resistance, are widely used in fine grinding and dispersion of different types of ceramics, enamels, glass, thick and hard materials in chemical plants. Alumina grinding ceramic beads are suitable for various ball mills, such as planetary ball mills, drum ball mills, stirring ball mills, vibration ball mills and other ball mills.
Product Features
1-High wear resistance: the wear resistance of alumina grinding ceramic beads is better than that of ordinary ceramic balls.
2-High purity: when the grinding ceramic bead is running, it will not produce pollution, so it can maintain high purity and improve the stability of grinding effect.
3-High density: high density, high hardness and high grinding can effectively improve the grinding effect.
4-High strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal shock stability, and stable chemical properties.
Product Application
Ball Stirred mill, Stripping machine, Polishing machine ,Sand mill etc.
