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 availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AGSAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball 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.
