Ceramic Grinding Media Balls
Introduction:
Alumina Grinding Balls are suitable for grinding medium used in ball grinding machines.
Alumina grinding ball is one ideal ball mill grinding media, it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.

Advantage:
High wear-resistance:
The alumina balls' wear-resistance is higher than the common alumina balls'. When it is working, the ball won't pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
High density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
The activated balls are widely utilized in the drying agent of multiform gas and liquid, also function is used as sorbent, desiccant, catalyst support in reactors for petrochemical industry, chemical industry, fertilizer industry and so on.
