Alumina balls are used at glass, porcelain enamel, abrasives, cement, pigment, and other ceramic factories, as well as paint factories, chemical factories, and weak electric appliance makers, as powder grinding media for pot mills, tube mills, and vibration mills.
 
Features:

1. High grinding efficiency: The high hardness and large specific gravity of the material itself enhance the grinding efficiency and shorten the grinding time.

2. Long life of balls: The wear resistance is as large as approx. five times that of ordinary porcelain balls.

3. The purity of ground substances can be kept high: The grinding loss of balls is small, and the quantity of abraded ball material mixed with the ground substances is small; therefore, the purity of ground substances can be kept high.

Material

α aluminium oxide by iso static pressing and high temperature tunnel kiln firing.
