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.
