Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Consequently, a method had to be found of introducing power into the mill so as to obtain a given specific energy input. For this purpose, stirring tests with purely Newtonian liquids were carried out in absence of solids and hence, without comminution. Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests

The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non-circular balls falls off rapidly. This reflects the
