of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.
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.
