ball mill pinion failure; Root cause analysis of bowlmill pinion shaft failures This article describes in detail the approach and root cause for failure of pinion shafts used in bowl mills of thermal power plants • This analysis clearly indicated that ceasing of the movement of the bowl mill segment all of a sudden due to hard, rocky lumps was the main cause for failure • Based …

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

Schematic of shaft and coupling assembly indicating the location of failure. Procedure adopted for root cause analysis is described below: 1. Visual examination and stereomicroscopy of the failed portions of the shaft. 2. Chemical analysis of the shaft material. 3.
