### Ball Mill an overview ScienceDirect Topics

Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L: D is, usually, accepted in the range 1.56–1.64.

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. You should see some discernible layer of product on top of the media. If you can actually see the media then is too little solids charge. Most solids will decrease in volume as the particle size is reduced, so you may have to add
