The ball charge, and hence the volume of the voids between the balls in the mill, is known and we are then able to calculate the factor 'volume pulp/volume voids between

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.
