The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%.

The ball mill filling can be estimated from the geometry of the ball charge at rest. However, in terms of the angle θ, ball filling (J B) may also be computed as indicated by Austin et al. . These relationships are illustrated in Figure 7.5. The charge centre of gravity may also be located in a similar graphical way as shown in Figure 7.6.
