95 Alumina ball:
It is an advanced process for mineral industry, expecially for copper industry to use high alumina balls as grinding media, The traditional process is to use steel balls as grinding media, But, during the grinding, the steel balls will dissolve in the acid liquid quickly. This will lead to a very low grinding effciency and even make it very difficult to separate the steel from the copper. But if with high alumina balls, the balls will not dissolve in the acid liquid and this will greatly improve the grinding efficiency and reduce the cost.
