SAG Mill Components Mineral ProcessingMetallurgy
Apr 18, 2018The obvious solution is to use more pinions, say, four per mill, with each pair coupled to the output shafts of a special single-input/double-output reducer — two reducers and two motors per mill. The problems of load division remain in this case, both in the reducers and in the motors. Another solution is to use the so-called “gearless drive.”

Sag Mill Dual Pinion Geared Drive
When mill power is between 18 and 20 MW, which is the current manufacturing limit of ring geared mills [2], either a gearless mill drive (GMD) or a ring geared mill with dual pinion motors can be chosen. Selecting between gearless or ring geared design is mostly dependent on size of the mill and power and speed requirements [3].
