How To Solve The High Temperature of The Ball Mill Main Bearing in Summer?

The main bearing of the ball mill is one of the important components of the ball mill, which has an important influence on the operation efficiency of the ball mill. Under the high temperature in summer, the main bearing of the ball mill is prone to high temperature of the bearing bush, and even a bearing accident may occur in severe cases, which will not only affect the operation of the ball mill but even affect the operation of the entire concentrator.

1. Replace ball mill lubricating oil in time

During the operation of the ball mill, heat is generated due to the relative rotational friction between the hollow shaft and the bearing bush, which increases the temperature of the main bearing. Therefore, the friction can be reduced by replacing the lubricating oil, so that a uniform oil film can be formed on the bearing surface, so as to avoid the temperature increase of the main bearing. During the inspection of the ball mill, the state of the lubricating oil should be checked in time, and the test should be carried out regularly. When the viscosity of the lubricating oil falls outside the allowable value range, the lubricating oil should be replaced in time.

2. Adjust the ball mill cooling device

The cooling water in the main bearing bush and the water in the main bearing oil tank cooler are the two main glasses of water for the main bearing of the ball mill. The temperature and amount of the cooling water have a great influence on the temperature of the main bearing of the ball mill. The cooling water temperature is low and the cooling effect is good. Increasing the cooling water flow also reduces the main bearing pad temperature.

In actual production, the cooler, cooling water pipeline, and large tile water jacket should also be cleaned in time. The cooling water and the lubricating oil exchange heat sufficiently to increase the cooling efficiency.

3. Improve the ball mill environment

Open the doors and windows of the factory building, the doors and windows of the oil pump room, and the observation hole of the large tile, improve the ventilation conditions of the environment where the ball mill is located, and reduce the temperature of the lubricating oil, thereby reducing the temperature of the large tile of the main bearing of the ball mill. In addition, spray water can be added to the oil return pipe and the oil outlet pipe to reduce the temperature.

4. Increase the cooling area of the oil pump

Re-select the cooler in the ball mill oil pump. Or connect the cooler in series to increase the cooling area of the ball mill lubricating oil, improve the heat exchange effect of the ball mill lubricating oil, and reduce the temperature of the lubricating oil fed into the ball mill, thereby reducing the bearing shell temperature.
