The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Analysis of Variant Ball Mill Drive Systems. The basic element of a ball mill is the drum, in which the milling process takes place (Figure 1). The length of the drum in the analyzed mill (without the lining) is 3.6 m, and the internal diameter is 3.4 m. The mass of the drum without the grinding media is 84 Mg.

At product sizes finer than 80% passing 75 μm, the efficiency of ball mill grinding rapidly decreases. The practical limit to ball mill product fineness is considered to be 40–45 μm (Gao and Weller, 1994). Although ball mills can still be found in the regrind circuits in a number of mineral processing plants, their energy consumption is ...
