In recent years, the production of ball mills has become larger, and the mechanical wear of traditional edge-driving ball mills is severe, and it has been difficult to meet production needs. Our company has conducted experimental research and found that improving the ball mill main bearings can significantly improve the production efficiency of the ball mills. It can also achieve the effect of saving electricity and water.

The mechanical loss of traditional edge drive ball mills is 10% ~ 14%, and the sliding bearing system that carries the main body load of the mill is the main part of energy loss. In the past, due to material properties, processing and other technologies, the main bearings of ball mills all used sliding bearing systems. The friction coefficient of the sliding bearing is about 0.04, and the friction coefficient of the energy-saving mill rolling bearing is 0.0025, which is only 1/16 of the friction coefficient of the sliding bearing. That is, the starting torque, running resistance and customer service mechanical friction resistance of the main friction friction mill are used. The power required is 16 times that of the rolling friction mill.

The ball mill bearing system was changed from a traditional sliding bearing to a rolling bearing, with a small amount of modification, short modification time, and low investment. It does not change the installation size and process parameters of the original machine. During use, rolling bearings are easy to maintain, reliable and pneumatic. Good performance, high carrying capacity at medium speed.

Rolling bearings are one of the most widely used components in modern machines, relying on rolling contact between the main components to support rotating parts. Compared with sliding bearings, rolling bearings have the advantages of convenient maintenance, low friction coefficient, low manufacturing cost, reliable work, good starting performance, and high load carrying capacity at medium speeds. In addition, the rolling bearing does not require a hydraulic station, which realizes fuel, water and power saving, and improves the equipment operation rate by 10% to 15%, which increases the economic benefits of the enterprise.

Our company found that after using rolling bearings, the ball mill has low running resistance, stable operation, and low failure rate, which eliminates the hidden danger of tile burning, and also increases the equipment operation rate and increases the economic benefits of the enterprise. Moreover, our company also found that after switching to rolling bearings, the main rolling bearings are lubricated with grease, which can eliminate the need for thin oil stations. The temperature rise of rolling bearings is also small and does not require water cooling. It can save costs by tens of thousands each year, and also improve The equipment production efficiency has realized the energy saving and efficiency increase of the ball mill.
