How to install and align the girth gear and pinion | prmdrive

Jan 14, 2020 · 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.

Pinion Shaft - an overview | ScienceDirect Topics

The gearless drive design was not applied to the mills in the mineral industry until 1981 when the then-world’s largest ball mill, 6.5 m diameter and 9.65 m long driven by a 8.1 MW motor, was installed at Sydvaranger in Norway (Meintrup and Kleiner, 1982).
