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.

The impact type sand making machine is used to produce and process high-quality machine-made sand. Industrial sectors such as building materials group, commercial concrete, highway viaduct and bridge construction, and hydropower stations need these concrete machine-made sand. The impact-type sand making machine is used in a machine-made sand. In the production line, it occupies an important position. It may be equipped with a single sand making machine, or it may be behind the head crusher (jaw crusher), second crusher (cone crusher or counterattack crusher) equipment.
