Jaw crusher, commonly known as jaw crusher, also known as tiger mouth, is an earlier crushing equipment. Because of its simple structure, sturdiness, reliable work, easy maintenance and repair, and relatively low production and construction costs, it is still widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries and many other sectors. The compressive strength has not been stained with various materials of 320 MPa. Due to the poor working nature of the jaw crusher, its components are susceptible to wear during production. Let's take a look at the reasons for the wear of the vulnerable parts of the jaw crusher.
 

During the operation of the crusher, some unexpected failures often occur, and the material blocking and tripping is one of them. When the crusher malfunctions, friends should not panic. All you have to do is to find out the cause, cure the "sickness" of the crusher, and prescribe the right medicine.

The crusher "eats too much and can't digest it", and it's not a big problem that jamming stops. That the main reason for the crusher's main machine to stop during crushing and blocking is that too much material accumulates in the small cavity of the crusher and can not be discharged out. It resists the moving cone and causes the motor to overload and stop. There are usually two situations that cause a trip.

Jaw crushers have the advantages of low noise, simple structure, reliable operation, etc., and are widely used, but often due to irregular operation or long-term component wear and other reasons, the discharge is not up to standard. Let's look at it in detail below: 　

The impact crusher plate is one of the main wearable parts of the counterattack crusher, and it plays an important role in the work of the equipment. Due to the serious wear of the impact crusher plate, it is necessary to choose a material with high wear resistance when selecting the material. What are the types of the impact crusher plate? How to choose? We introduce the material of the impact plate of the impact crusher from the following two points.

1, The hydraulic cone crusher adopts hydraulic protection and hydraulic chamber cleaning, which is convenient for maintenance and short downtime, which greatly reduces the trouble of manual unloading when the original spring cone crusher needs to be closed. 　
　
2, The iron protection device of the hydraulic cone crusher, when the sundries enter the cavity, the protection device will automatically release, and then reset immediately, without affecting the normal operation of the equipment. However, the protection stroke of the spring cone crusher is short, which sometimes causes serious accidents, such as shaft breakage.
