Alumina Grinding Balls are suitable for grinding medium used in ball grinding machines.
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.
The alumina balls ’ wear-resistance is higher than the common alumina balls’,it have many advantages ,such as :high density, corrosion-resistance, high mechanical strength and great wear-resistance. It is an economical, widely-used and non-metallic grinding media.

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.
