Jaw Crusher is the widely used crushing machine in mining, smelting, building materials, road, railway, water conservancy and chemical industries. It is mainly used to crush mined mineral raw materials into materials suitable for transportation, use and grinding. It has the advantages of simple structure, reliable work, convenient operation and low production cost. Due to the long and heavy working time, harsh working environment and complicated stress situation of jaw crusher, faults often occur to production. Therefore, the correct operation and regular maintenance of jaw crusher are related to the utilization rate of equipment, service life, production cost, economic benefits of enterprises and other factors. So, what measures can make jaw crusher keep " youth" forever? Li Ming Heavy Industry experts will help you today!
First, " checking". Check whether the main components are in good condition, whether the fastening bolts and other connecting pieces are loose, whether the safety device is complete, whether the lubricating device is in good condition, whether the cooling water pipe valve is open, etc. These is all fine work. Don't be careless.
Second, strict operation. The staff must operate in strict accordance with the operating rules. When starting the main motor, pay attention to the ammeter indication on the control cabinet. After 20 to 30 seconds, the current will drop to the normal working current value. Adjust and control the feeding so that the feeding is uniform and the feeding size does not exceed 80 % - 90 % of the width of the inlet. Pay attention to the temperature of the bearing. Generally, the temperature of the sliding bearing should not exceed 60 ℃ and the temperature of the rolling bearing should not exceed 70 ℃. If the electrical equipment trips automatically, the reason should be found out immediately and it is strictly prohibited to start continuously.
Third, the use of lubricating oil is an essential link in the maintenance of jaw crusher. The connecting rod bearing, eccentric shaft bearing, thrust plate elbow need lubricating oil. It is more appropriate to use No. 70 machine oil in summer and No. 40 machine oil in winter. If the crusher often works continuously and there is a lubricating oil heating device in winter, it can be heated in advance, and the external temperature in summer is not too high, No. 50machine oil can be used for lubrication.
Mastering the basic knowledge of correct operation and maintenance of jaw crusher is great significance to guarantee the stability, reliability and operation of the machine and extend its service life.
