Cone crushers are widely favored by customers due to their large crushing ratio and high efficiency performance characteristics. However, we often do not know how to maintain and maintain the machine during use, which will easily cause the machine to fail to operate normally. The maintenance of cone crusher needs to pay attention to several aspects.

The rotor plays an important role in the sand making machine. It is a relatively important part of the sand making machine equipment. The sand and gravel processing materials are mainly crushed and shaped here. The accumulation of materials is a normal phenomenon. Insufficient accumulation of materials will cause the ejection head to be excessive. Early wear and tear will cause the throwing head to fall off from the clamping block grinding plate; too much accumulation of material will also cause friction with the rotor, which will affect the service life of the rotor. Let me talk about how the rotor adjusts the accumulation of material.

Recently, the market of sand and gravel aggregates is very good. It has entered the peak period of sand and gravel crushing equipment operation. However, many friends still encounter some failures, such as abnormal vibration of the machine. This time we will talk about the common abnormal vibration of cone crushers. the reason.

The oil leakage of the cone crusher is one of the common faults. There are 4 main reasons: ①The sealing device is invalid ②The oil return pipe is blocked ③The working pressure is improper ④The component gap is unreasonable. The preventive measures are as follows.
 

The jaw crusher works under impact load. The babbitt alloy lining on the bearing bush has a working period of about 2 years. If it exceeds the period, it needs to be recast.
 
If the shaft wears very little, just to repair its geometric shape, it can be turned on a lathe to make the shaft journal reach the correct geometric shape, and then reduce the bearing inner diameter accordingly. However, after several such treatments, if the journal size is reduced by 5% compared to the original, turning is not allowed, and a new shaft should be replaced.
