92% Alumina Ceramic Grinding Balls With High Wear Resistance
92% Alumina Ceramic Ball
Description
Our alumina ceramic ball is made of α alumina (α-aluminium oxide, the most thermodynamically stable form) by cool isostatic pressing or rolling, then fired at a very high temperature in the tunnel kiln. Alumina grinding ball/beads is suitable for both wet and dry superfine grinding of alumina, zirconia silicate, feldspar, quartz, kaolin clay, glaze, inks and ceramics in Stirred and ball mill.
