How does the jaw crusher crush granite

 When crushing granite with a jaw crusher, the granite blocks are loaded into the mouth between the tooth plates from the upper part of the crusher, and gradually descend after being crushed. When the jaw crusher is crushing, part of its force is pressure and part is impact.
 

When loading granite into the jaw crusher, it should be evenly loaded on the side of the fixed tooth plate along the width of the entire charging port. The particle size of the granite loaded into the jaw crusher should not be larger than the charging port, otherwise the crusher will be blocked, which will easily cause the jaw crusher to stop and reduce the flow rate.

After starting the jaw crusher, you should wait until the shaking times are normal before loading granite. Using the mechanized charging method, if it is necessary to stop the operation of the jaw crusher, the feeder must be stopped first, and the crusher equipment can only be stopped after all the granite in the charging port is completely broken; if it is due to a power failure or a transmission belt When you need to stop due to an accident such as taking off, stop the feeder immediately. After eliminating the fault that caused the shutdown, remove the remaining granite in the crusher, and then start the jaw crusher according to the above rules.

All worn parts of the jaw crusher should be carefully lubricated. Therefore, during the working process of the jaw crusher, care must be taken to add oil to the oil tank that supplies fresh lubricating oil in time. When adding oil to the oil gu, it must be pressed until the new oil layer overflows from the gap between the journal and the bearing. The appearance of a new lubricating oil layer indicates that the waste lubricating oil has been pressed out by the new lubricating oil, and the lubricating oil hole is not blocked.
