what is the solution to the failure of the ball mill gear. the bearings of the gear reducer failures on input bearings are the most common have a life time of down to to years mainly reduced due to the starting stress the change of the bearings is linked to a major overhaul the life time of gear reducers are not matching the life time expectations of the mill and need to be replaced
So it is a large synchronous motor coupled to a stub shaft, coupled to the pinon and it meshes with the bullgear that is on the outer circumference of the mill. Pinion speed is indeed 180. Bull gear tooth count is 241. I had a cage failure on one of the pinion bearing 2 years ago, at
Aug 28, 2011 Re Ball Mill Girth Gear and Pinion Alignment 08272011 207 AM pinion alighnment is done by coating the pinion with a lead based grease. after rotating the drum, the grease marks will show the contact area. the pinion should contact the girth ring near the center of the gears.

Apr 01, 2013 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.
In the daily production of the ball mill, there will always be some sudden failures, such as severe vibration of the ball mill gear, cracking of the large gear ring of the ball mill, or the sudden increase in the temperature of the ball mill bearing. accident. Fodamon engineers shares the reasons and solutions of the severe vibration of the ball mill pinion.
Jun 05, 2019 An enterprise maintenance personnel found that the vibration of the pinion shaft bearing housing of the ball mill reducer is relatively large, and the bearing temperature is continuously rising. In this case, the emergency stop, the inspection of the pinion shaft bearing seat, the bearing of the pinion shaft support side is seriously damaged, and the bearing position is seriously worn.
Oct 19, 2016 1. Establish vertical and horizontal centerline of mill and pinion shaft against the effects of this, we recommend that the trunnion bearing sole plate be crowned so as to be higher at the center line of the mill. This is done by using a higher shim at the center than at the ends and tightening the foundation bolts of both ends. Ball Mill Sole ...
