Sag Mill Dual Pinion Geared Drive :

An electrical impact study between variable speed dual ...

2015-10-22  When mill power is between 18 and 20 MW, which is the current manufacturing limit of ring geared mills, 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
