The sizes of our products are divided into 0.5mm,2mm,3mm,4mm,6mm,8mm,10mm,20mm,30mm,40mm,50mm and 60mm.,70mm,80mm,90mm.This series is widely used in ceramic industry for grinding materials, especially in architectural pottery and fine chemcial industry for ball-milling glaze and raw materials.



Main Advantages

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
