High alumina ball means alumina ball with aluminium oxide content higher than 90%, high alumina ball is high efficiency grinding media in today industry. The high alumina ball works together with the high alumina mill linings brick will benefits you:

> Less grinding time, doubled productivity.
> Less wear loss of the ball and linings, more clean you final product keep.
> Longer service life, less down time
