Nearly one user reported that the bearing temperature of ore grinding mill was very high. In addition to considering the influence of high temperature in summer, he was also worried that the normal operation of ore grinding mill would be affected by the high temperature of ore grinding mill. What happened to the high bearing temperature of ore grinding mill?

Bearings are the main supporting parts in the operation of grinding equipment. Bearings are also the main factors affecting the performance and production efficiency of ore grinding mill. Users must pay special attention to the temperature of bearings and the noise of bearings in order to avoid abnormal phenomena and affect the normal operation of the machine. So what are the factors that cause the ore grinding mill? How to solve it? Too much or too little lubricating oil will cause the bearing to heat up. If the heat dissipation performance is not good, the heat generated can not be released in time; and too little will not completely lubricate the bearing. In the case of high-speed operation, the bearing will heat up. When lubricating oil is added to the bearing, the general lubricating oil takes up space. About 70% is good, too much or too little is not conducive to the heat dissipation of bearings.

In addition, if the bearing height is different, or the motor rotor and the mill rotor are not centrifugal, it will lead to additional coincidence impact of the bearing, leading to the phenomenon of bearing overheating. If this phenomenon occurs, the bearing position should be adjusted immediately to avoid the phenomenon of eccentric wear. Another is that the bearing and bearing seat of the ore grinding mill are too tight, which leads to worsening wear and tear. If it is too loose, it will also lead to overheating of the bearing. This kind of problem arises. It is necessary to adjust the tightness of the bearing and bearing seat to re-match.

No matter what causes the bearing overheating of ore grinding mill, shut down the machine and equipment first, and find out and solve the machine fault in time, so as to avoid delaying normal production and operation and causing unnecessary losses.
