optimization of the ball charge in a grinding mill
Sino Grinding Grinding Media
Larger grinding media has a smaller grinding surface area but offers a heavier weight that s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases we find ourselves adjusting the ball size by the millimeter to approach optimization.
