Product Details

Alumina grinding balls for support media 95%Al2O3

High alumina grinding ceramic ball:

92%Al2O3 grinding ceramic ball, 95%Al2O3 grinding ceramic ball

Middle alumina grinding ceramic ball:

Micro-crystal middle alumina, carborundum middle alumina

High alumina grinding ceramic ball:

High alumina grinding ceramic balls are made from selected raw materials and fired in high temperature by advanced technique and automatic molding process using cool isostatic press. The ball serial includes various diameters ranging from 25mm to 75mm.

Advantages:

Compared with natural stone balls and normal ceramic balls, alumina grinding ball increases by 20-40 times in its performance of wear resistance.

Its grinding efficiency improves by 40%-60% and ball mill efficiency add by 30%-40%. Their total costs only take 40-60 percent of that of natural stone balls.
