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.

The operating principle of the ball mill

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

The "pulverisette 4" vario-planetary mill is capable of emulating ball mills of conventional design, simulating the types of stress entailed and thus reproduc-ing or optimising grinding processes. Due to the high flexibility available for se-lecting the grinding parameters, it is possible to achieve results unattainable with any other ball mills.
