Ball Mill Loading
The starting point for ball mill media and solids charging generally starts as follows: Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading. Empirical Check: Once the mill has been loaded and run for a few minutes, open the cover and look down into the mill.
