How can I do the daily maintenance work of ultra-fine grinding bearings?

Ultra-fine grinding is a main equipment for grinding in the next step after the material is crushed. The ultra-fine grinding materials suitable for grinding are mainly quartz stone, gold ore, iron ore, cement clinker, copper ore, pyrrhotite, Construction waste, glass, etc. Because of its practicality, it is recognized by customers.

Then the problem has come. Many customers have purchased ultra-fine grinding. It has not been used for a few years. The efficiency of ultra-fine grinding is not as high as before. There are also various problems, which makes customers very distressed and superfine grinding faults. It not only affects the construction period, but also affects the customer's income, and has invested a lot of cost. How can we make the quality of ultra-fine grinding unchanged and prolong the service life? Let's analyze the reasons for this.

Ultra fine grinding efficiency is not as good as new machines

Many customers use ultra-fine grinding, which often overlooks a problem. It is the lubrication of super-fine grinding sliding bearings. The sliding bearing is the key part that carries the normal operation of ultra-fine grinding. If it is working in ultra-fine grinding, the sliding bearing is not well lubricated. If the sealing is not strict, the sliding bearing will be damaged, and then the lubricating oil will be contaminated by the particulate dust inside the crushing chamber, resulting in impure lubrication inside the bearing, which affects the working efficiency of the entire ultra-fine grinding. Lubricated bearings are severely worn, and the temperature inside the chamber will rise sharply, causing the burnt bearing to burn out and the service life is less than one year. Lubricated bearings are poorly lubricated and are the main cause of superfine grinding failures.


How to do the protection work of lubricating bearings

Whether the lubrication bearing is good or bad directly affects the overall operation of the ultra-fine grinding, how can we do the daily maintenance work of the ultra-fine grinding bearing? The focus is coming, please continue to look down.

First, before starting the ultra-fine grinding, start the oil pump first, and then start the ultra-fine grinding after the oil pump runs for two minutes. Use the PC automatic control system. When the oil pump can't continue to supply oil, it will give an alarm. At this time, stop the super immediately. Finely ground running. Secondly, a temperature sensor is installed on each sliding bearing. When the oil supply is too small or the sliding bearing temperature rises to 55 °C due to other reasons, the control system will alarm and the ultra-fine grinding will automatically stop. Furthermore, in order to ensure that the lubricating bearing can obtain better lubrication, the oil storage tank is installed on the inlet pipe of each sliding bearing, and even in the event of a failure of the oil supply system, the lubricating oil in the oil storage tank can rely on its own gravity. Flow out to achieve the effect of lubrication.

As long as the lubrication of the above lubricated bearings is done well, the ultra-fine grinding you have has a longer life than the ultra-fine grinding of other customers. The service life of ultra-fine grinding will not exceed the service life. cut back.
