Reason: One of the possible reasons for the ball mill reducer bearing heating is insufficient lubrication. Insufficient lubrication can cause bearings to operate at high temperatures, resulting in overheating.

Another cause could be excessive load or improper installation. When equipment is subjected to heavier loads than it can handle, it stresses the bearings, causing overheating. Likewise, if the bearings are installed incorrectly or misaligned between the shafts, this can lead to increased friction and heat generation.

Solution: To solve this problem, regularly checking and replenishing the lubricating oil in the reducer is necessary. A high-quality and suitable lubricant can also help reduce friction and heat generation. Proper load management and accurate installation procedures also need to be ensured.
