Outstanding:
Ideal Alumina grinding ball to keep the purity and improve the stability of grinded materials
Used in ball grinding machines .
Advantage:
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.
