Last Update:2020-05-07 10:50:11

With the continuous development of China's coal industry, mining is becoming more and more modern chemical industry, most of which use coal mine underground crusher for operation, which improves the position of the equipment in the market. The crusher is mainly used in the mining work of the coal industry, which greatly promotes the development of the coal industry in China. In the process of using the equipment, operators need to pay attention to the details of maintenance. Below for you to introduce the coal mine underground crusher maintenance matters.

In the process of working with the crusher in the coal mine, the operator stopped the machine and checked it regularly. No matter what kind of material is crushed, the operator should stop the machine regularly to check the internal wear of the equipment, especially the central feeding pipe, cone cap, impeller upper and lower runner lining plates and other places that are easy to wear. For parts with serious wear, they must be replaced or repaired in time. At the same time, the operator should also put the lubrication of all components of the downhole crusher in the front position, and regularly check the condition of the lubricating oil.

When the underground crusher operates for more than 2000 hours, the operator must open the main shaft to clean the bearing. When it works for 7200 hours, it needs to replace the new bearing to ensure the normal and orderly operation of the equipment. Operators also need to check the drive belt of the equipment regularly, because the normal operation of the equipment is the credit of the drive belt. Ensure that the conveyor belt of the underground crusher is properly tightened and evenly stressed. If it is found that the conveyor belt of the underground crusher is seriously worn, it needs to be replaced in time. Otherwise, there will be more serious consequences.

In addition, in order to ensure the long-term normal operation of the crusher used in the coal mine, in addition to the correct operation and maintenance of the equipment, it also needs to carry out planned maintenance work, mainly including minor repair, medium repair and overhaul of the equipment. Excellent when the equipment is operated for about 1-3 months, the interval of minor repair is about 1-2 years, and the overhaul cycle is relatively longer, mainly replacing the vulnerable parts and core components of the underground crusher, the general cycle is about 5 years.
