Abstract
Existing ball mills of drum type are analyzed. Their advantages and disadvantages are identified. Possible means of improving the grinding efficiency are noted. A fundamentally new ball design is proposed. Equations are derived for calculating the total and consumed power in transverse and longitudinal ball motion within both drum chambers. Formulas are presented for the loading factor and the power consumed. As an example, the maximum permissible loading factor for a drum is calculated, as well as the drive’s additional power consumption. A nomogram is presented for determining the loading factor. The influence of the ball mass on the power consumption is shown graphically.
