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.

It is very necessary for the staff to do the daily maintenance of the jaw crusher, which can make the jaw crusher work in a better state, which is beneficial to the production of the enterprise. Let’s talk about the maintenance of the jaw crusher. Skills, I hope it can be helpful to our customers. The five points are as follows:

The cone crusher mainly crushes large rocks. During the crushing process, high-speed rotation and collision will inevitably produce noise, which will affect the health of workers and cause partial damage to the equipment. What are the reasons for the noise of the crusher? The following introduces the causes and solutions of cone crusher noise: 　

As a large-scale equipment, the cone crusher works in the open air all the year round. It is very important to do the maintenance work of the cone crusher. When it comes to maintenance, it is inseparable from the lubricating oil. So how to choose the lubricating oil for the cone crusher?
