SAG Mill Components 911 Metallurgist

Apr 18, 2018· If the mill requires approximately 6000 horsepower or less, it is possible to drive it with a single pinion. To date, however, economics has dictated that most mills over 3500 horsepower be driven with two pinions, using wound rotor motors driving thru speed reducers.

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.
