Projects Improving Mechanical Ball Mills

  • TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS …

    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.
