Abstract Size reduction is the operation carried out for reducing the size of bigger particle into smaller one by external forces. This reducing in size is done by using ball mill. In the experiment, the stone are weight about 100g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 90rpm.
