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.
In this paper, we carried out batch grinding tests of silica glass, limestone and gypsum with a ball mill and investigated the effects of feed size and ball diameter on the grinding rate constant (selection function). The results are summarized as follows 1.

Dry grinding experiments on cement clinker were carried out using a laboratory batch ball mill equipped with a torque measurement. The influence of the ball size distribution on the specific selection function can be approached by laboratory runs using monosize balls.

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the These operations are characterized by two functions: the selection function Si,
