Jaw crushing machine is abbreviated as jaw crusher. Application of jaw crusher: gravel yard, mining, coal mining, concrete mixing station, dry mortar, power plant desulfurization, quartz sand. It can crush a variety of materials whose pressure resistance does not exceed 320 MPa. Driving extrusion is the working mode of jaw crusher. Jaw crushers belong to rough and medium crushing equipment in crushing production. How to maintain jaw crusher during use can reduce the failure of the equipment and increase the service life?

Daily maintenance of jaw crusher

1. To check the heating of the rolling bearing. For rolling bearings, the heat cannot exceed 70°C, and for sliding bearings, the heat cannot exceed 60°C. If the heat exceeds the prescribed standard, you should stop immediately for inspection and troubleshooting.

2. To check whether the lubrication system is operating normally, whether the gear pump is working or not. To check the index value of the oil pressure gauge and to check whether the oil in the oil tank is sufficient, and whether there is oil leakage. If you find that these components have problems, you should deal with them in time. Suspend the shaft plate and shaft head, and use manual or automatic dry oil pump to regularly inject oil. The small crushing motor suspension bearing is added with a butter cup, approximately every 40-60 minutes. Add oil to the elbow of the bracket every 3-4h.

3. To check whether there are other materials such as metal powder in the oil. If there are other materials, stop and open the bearing and other parts for investigation.

4. To check whether the connecting parts such as bolts and flywheel keys are loose.

5. To check the wear of the gear plate and transmission parts, and to check whether the pull rod spring is operating normally.

6. Frequent cleaning operations should be carried out to ensure that there is no dust, no stains, no oil leakage, water leakage, or electricity leakage, especially to prevent dust from entering the lubricating components.

7. To clean the filter cooler regularly. After cleaning, it should be completely dried before use.

8. Regularly replace the lubricating grease in the oil tank, usually every 6 months. Analysis and solution of common failures of jaw crusher After the crusher has been used for a long time, the parts or matching parts will exhaust the performance of the initial operation due to wear, bending, fatigue, corrosion, looseness or other reasons, which will deteriorate the technical condition of the crusher and cause abnormal work and it can not continue the operation. So

how to solve the failure of the crusher at this time?

The failure problems of the jaw crusher include: the matching relationship of the normal matching parts is damaged. The relative position between the structural parts changes. The parts themselves are deformed and damaged. The material changes and the surface quality changes. The impurity between the structural parts is blocked.

The reasons for the failure of the jaw crusher mainly include accidental damage (such as blockage, shaking) caused by improper adjustment, usage, and repair, and the natural destruction of its parts due to wear, corrosion, corrosion, fatigue and other reasons. The first one can be avoided, although the latter one cannot be avoided, but if the cause of damage to the parts can be found out, the regularity of the damage can be grasped, and effective technical measures shall be taken in every link from design, manufacturing to use and maintenance. The above regulations can greatly reduce the damage of parts and increase the service life of the machine. Jaw crusher lubrication

1. Under normal circumstances, pay attention to the friction surface and lubricate it in time, and then use the normal operation of the jaw to increase the service life.

2. For the calcium-based lubricating oil often used in machines, users can also choose other models according to the location, temperature and grease of the machine, but they need to have well-lubricated bearing protection.

3. Add 50-70% of the grease to the bearing and replace the grease once every three months. When changing the engine oil, clean gasoline and kerosene, and carefully clean the steel ball slide.
