The cost of edge drive is low, but the pinion needs to be replaced every 25 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.

The details of the ball mill motor are as follows. Power = kW or HP and the speed is 343 rpm. Load calculations (prior to failure analysis) The ball mill can experience failure based on the maximum normal stress theory as the working loads acting in the ball mill is concentrated across the seam of the mill periphery.

Ignoring mechanical losses in this drive train, the power transmission at each stage, defined as torque x speed, is constant. The typical mechanical inching drive motor speed is around 1500 to 1800 RPM while the mill inching speed is in the order of to RPM. Thus, the gear reduction ratio between the inching drive motor and the mill is ...
