Advantage

 

High wear-resistance:The alumina balls wear-resistance is higher than the common alumina balls. When it is working, the ball wont pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.

High densityThe high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
