The power of a ball mill is obtained by multiplying the corresponding torque with the mill speed. Thus, the torque curves and power curves are similar. Fig. 20 shows 78 groups of DEM simulation results for the effect of rotation rate, lifter height, and lifter number on the power draw of the ball mill. Each curve represents the variation of the ...
Motor selection can become still more complex when loads do not exhibit a single speedtorque curve, or for which torque at full speed varies throughout each revolution. One example is the large ball mill used in minerals processing.

The torque speed characteristic of a typical ball mill is shown in Figure 1. On this curve there are three distinctive points of interest, which uniquely characterize the ball mill operation. Figure 1 a) The breakaway from rest is identified as the region on the graph requiring 40% to 70% of nominal torque from rest to approximately 20% speed.
Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages.
