We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates. Typical tests required to define a hardness variability function, are given below in Figure 1.

Semi-Autogenous (SAG) Mills. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15%, and is primarily been used in the gold, copper and platinum industries but also in the lead, zinc, silver, and nickel industries. Autogenous (AG) Mills. Autogenous grinding involves no grinding media as the ore itself is the grinding media.

This calculator analyses the granulometry of the material inside the mill and proposes a modification of the ball charge in order to improve the mill …

For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles; therefore, the size at which the S value becomes maximum, x m, increases as the ball size becomes larger.

Past ball mill studies have evaluated the importance of many factors in ball mill grinding efficiency including ball size distribution, mill length to diameter ratio, compartment lengths, mill rotational speed, and mill filling percentage.

The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change.
