    Add to this another 45% to 50% above the ball charge for total of 58% to 63% product loading. This level of liquid loading should leave some air space above the liquid to allow for expansion of the liquid as it heats up during the milling process. So as a rule of thumb we use a maximum of 60% liquid loading.
