torque of this ball mill is about 78%, far below the rated torque level. Possibly this is a consequence of starting the mill extremely gently. The drive system has however been oversized to deliver 150% starting torque. The other fascinating issue is that this ball mill is apparently not a truly constant torque .

TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL .

general, the bigger the mill diameter, the lower are the mill operating and critical speeds. Thus, for larger mills the number of poles will increase. As a result, the number of poles can vary from 48 to 72 poles (Fig. 3.) with typical mill speed requirements of about 10 rpm for larger SAG mills and about 15 rpm for smaller ball mills. Figure 3.
