Abstract: The grinding roller is the core component of the TRM vertical mill, and the grinding roller bearing, as a key part of the grinding roller, directly affects the normal operation of the mill and the stability of the production line, making maintenance work crucial. Proper lubrication is key to the maintenance of grinding roller bearings. Firstly, it is essential to clarify that the main lubrication methods employed are circulating lubrication and oil bath lubrication. The selection of suitable lubricating oil should be based on actual working conditions, and the inspection and replacement specifications for lubricating oil must be strictly followed. Secondly, ensuring the stable operation of grinding roller bearings requires attention to oil temperature control, vibration monitoring, and sealing quality. Oil temperature is managed in real-time through a dedicated monitoring system, vibration data is collected and analyzed using online monitoring and fault diagnosis systems, and sealing is achieved through a combination of lip seals and "V-ring seals + gas seals". Finally, the preparatory work and assembly precautions for the on-site assembly and maintenance of grinding roller bearings are detailed. It is also pointed out that factors such as vibration and overload operation during production can affect the service life of grinding roller bearings, necessitating targeted preventive measures to effectively extend their service cycle.
