22.jpgGrinding ball mills, like cement mills, are working day and night without pause. Various problems may have after a period of operation. For example, the over temperature of the bearings. Why did this happen? We will have an experience sharing with you today.

1. Along with the time, the viscosity of the lubricating oil will be different with its initial. The quality of the oil is getting worse. Elastohydrodynamic lubrication is easy to be caused, thus it had a bad affection on the final lubricating function and lead to a high temperature of the bearing.

2. Usually, the slide-shoe bearing is equipped with a cooling installation. If this installation is in troubles, such as, be blocked, the temperature will be rising too.

3. We know that the lubrication pipe and the water-cooled tube are installed in the same shell. Sometimes, if water is outflow from the cooling pipe, it affects the oil in the return pipe directly. For instance, emulsion problem→→bad quality→high temperature of the bearings.

4. Hydrodynamic lubricationis where the motion of the contacting surfaces and the exact design of the bearing is used to pump lubricant around the bearing to maintain the lubricating film. This design of bearing may wear when started, stopped or reversed, as the lubricant film breaks down.
