There are some guidelines as to the % of total mill volume occupied by ore+grinding media+water. And this generally depends on the type of mill you are using (i.e. ball, rod, SAG, AG, UFG, etc…), although there are some overlaps between.

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.

In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

The fraction of the mill volume occupied by the mill charge can be estimated based on a ratio of the cross-sectional areas. The cross-sectional area of the mill charge (A C) can be determined from: Aâ†"C = Hâ†"B / 6W (3Hâ†"Bâ†'2 + 4Wâ†'2)
