Figure 8.3 Simplified calculation of the torque required to turn a mill. RI FULWLFDO VSHHG mill is the energy consumption. The power supplied to the mill is used primarily to lift the load approach to modeling of mill power draw. Trans. Instn. Mining. Metall. (Sect C:Mineral Processing Extr Metall.) 105, January-April 1996 ppC54-C62.

The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

Calculation of the power draw of dry multi-compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.
