Alumina Grinding Ball Return on a page
XINGFENG Grinding Balls are suitable for grinding medium used in ball grinding machines.

Alumina grinding ball has been widely used in ball mills as abrasive media for ceramic raw materals and glaze materials in ceramic factors, cement factories, enamel factories and glasswork owing to the extraordinarily high density, high hardness, high wear resistance.During the abrasive/grinding processes, ceramic aballs will not be broken, it will not comtaminate the materials to be grinded.

Type: 65 Alumina ball, 75 Alumina ball, 90 Alumina ball, 92 Alumina ball, 95 Alumina ball, 99 Alumina ball etc

Advantage

(1) 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.

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