The ball mill trunnion bearing is one of the most crucial parts in the ball mill. It is responsible for supporting the entire weight of the mill, and hence, plays a critical role in maintaining its structural integrity. Therefore, it is essential to keep the trunnion bearing well lubricated to ensure optimal performance and prolong its lifespan. The trunnion bearing lubrication system is designed to provide adequate cooling and lubrication to the bearings, ensuring optimal functioning of the mill.
In this blog post, we will discuss the trunnion bearing ball mill lubrication system in detail, including its components, working principle, and maintenance.
Components of the trunnion bearing ball mill lubrication system
The trunnion bearing ball mill lubrication system comprises of an oil reservoir, a pump, a filter, and the necessary piping and instrumentation to control the flow of the oil. The lubrication system is designed to provide low pressure oil for cooling and lubrication of the bearings, and high-pressure oil for hydrostatic lift of the feed and discharge trunnions during start-up of the mill.
Working principle of the trunnion bearing ball mill lubrication system
The oil in the oil reservoir is pumped through the filter and cooler to the low-pressure oil supply manifold. From there, the oil is directed to the bearings via individual flow meters, which regulate the oil flow to each bearing. The oil collects in the bearings and flows back to the reservoir via drain pipes. Additionally, high-pressure oil is provided to the feed and discharge trunnions through separate high-pressure pumps to hydrostatically lift the mill during start-up.
The system is equipped with pressure switches to monitor the oil pressure and flow meters to measure the oil flow rate. The temperature of the oil is also monitored to ensure that it remains within the specified range.
Maintenance of the trunnion bearing ball mill lubrication system
The trunnion bearing ball mill lubrication system requires periodic maintenance to ensure that it functions properly. The main components that need to be checked and maintained include the oil reservoir, pumps, filters, flow meters, and temperature sensors.
The oil reservoir should be inspected regularly to ensure that it is clean and the oil level is adequate. If the oil level is low, it should be topped up immediately. The pumps and filters should be checked periodically to ensure that they are working correctly, and any clogs are removed.
The flow meters should be checked to ensure that they are reading accurately, and any deviations should be corrected. Similarly, the temperature sensors should be checked to ensure that they are giving the correct readings, and any issues should be investigated.
Conclusion
The trunnion bearing ball mill lubrication system is a critical part of the ball mill. It ensures that the bearings remain cool and lubricated, ensuring optimal functioning of the mill. Therefore, it is essential to ensure that the system is maintained properly to avoid any breakdowns or equipment failures. Regular inspections and maintenance of the components can help prolong the life of the system and avoid any costly repairs or replacements.
