Rotary kiln as a kind of high temperature equipment, the most important thing during the protection of its components is to prevent the harms of high temperature. Among them, it is necessary to pay attention to the problem of temperature rise of the bearing during the operation of the rotary kiln. This must be noted. This article will give a brief explanation of this issue.

First of all, we need to clearly understand what is the cause of the heating up of the rotary kiln's bearings. To check whether it is because the rotary kiln support roller shaft seal is not good, the oil leakage leads to a serious reduction of the oil level, or the lubricating oil spoon fall off to cause the bearing temperature increases, if it is for this reason, we must replace seal ring and fasten lubricating oil spoon. The main cause of the problem is the sealing of the rotary kiln support roller. Therefore, the most effective solution is to strictly require the sealing of the equipment during the initial design process, to ensure good sealing of the rotary kiln support roller.

In addition, when the temperature of the rotary kiln bearing is increased, it is also necessary to analyze the factors that the circulating water is not smooth or the amount of water is small. When the circulating water pipe inside the rotary kiln support roller ages and causes water leakage, the viscosity of the lubricating oil is destroyed, and then the heating-up of bearing is caused. At this time, we must first clear the circulating water pipe with acid to remove internal impurities, and replace the damaged internal water pipe. 

After all these tasks are completed, we must also check the lubricating oil of the rotary kiln support roller bearing to see if the lubricating oil isn’t changed for a long time or isn’t maintained properly, which results in viscosity decrease of the lubricating oil, oil emulsification, or dust contained in the oil, and then causes the heating up of bearing, the best way to deal with is to regularly replace the new oil, and strengthen the maintenance of the support roller bearing. 

In summary, the common reasons for the heating-up of the rotary kiln bearing shell include the sealing problem of rotary kiln support roller, the problem of internal circulating water pipes and water volume, and the problem of the lubrication oil of the rotary kiln. After finding the cause of the problems, it can be better to solve temperature rise of rotary kiln bearings.
