What causes the phenomenon of excessive temperature in the ball mill bearings? This article provides a detailed analysis of this issue, as follows: 1. The viscosity of the lubricating oil changes with the increase in usage time, leading to a decline in oil quality, which affects the formation of hydrodynamic lubrication and thus impacts the lubrication effect, causing the bearing temperature to rise. 2. The sliding bearings used in ball mills are relatively large, and they usually have powerful cooling devices. If the cooling device malfunctions, such as clogging, it can lead to poor cooling effects, which may also cause the bearing temperature to rise. 3. The cooling water pipes of the ball mill sliding bearings and the lubricating oil pipes are within the same casing.

2. The sliding bearings used in ball mills are relatively large, and they usually have powerful cooling devices. If the cooling device malfunctions, such as clogging, it will result in poor cooling effect, which may also cause the bearing temperature to rise.
3. The cooling water pipes and lubricating oil pipes of the ball mill sliding bearings are within the same housing. If there is a leakage in the cooling water system, water will enter the return oil, causing oil emulsification, degrading its quality, and worsening the lubrication effect, which may also lead to an increase in bearing temperature.
4. The formation of the hydrodynamic oil film requires a certain amount of time and oil supply. If there is insufficient oil supply between the friction pairs, and there is not enough oil to be brought into the friction pairs, hydrodynamic lubrication cannot be achieved, resulting in a deterioration of the lubrication effect.
