Ideal Alumina grinding ball to keep the purity and improve the stability of grinded materials
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.
