The ball mill has a load every time it starts, so it has a great influence on various components and equipment such as motors, reducers, bearings and large and small gears. Frequent startup increases the load of components, increases the failure rate of equipment, and reduces equipment. The service life.
The bearing is one of the important parts of the ball mill, which will affects the efficiency and service life of ball mill.Therefore, a good bearing is very important to the ball mill. Sometimes, there will be some problems on the bearing of ball mill, how to solve the problems?

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 .
Jul 16, 2003· I've worked with girth gear problems in many plants, on various rotary kilns & ball mills (up to 5000 hp). The previous responders are spot on regarding the cause of pitting. There are some additional methods for correcting pitting on the girth gear regarding carburized pinions and machine in place technology.
