Combination Pinion Stands
Combination pinion stands are the combination of a gear reducer and a pinion stand in one unit. The output shaft speed and torque are proportional to the reduction ratio of the internal gearing. Combination pinion stands are generally used when space constraints limit the drive arrangement for a bar mill or a cold mill.

How to install and align the girth gear and pinion | prmdrive
The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear (big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

An electrical impact study between variable speed dual pinion mills and ...
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].
