Maintenance method of jaw crusher

Have a general understanding of the factors that affect the production capacity of the jaw crusher. Generally speaking, there are many factors that affect the production capacity of jaw crushers.

1. Material hardness: the harder the material, the more difficult it is to break, and the more severe the wear on the equipment. The crushing speed is slow and the productivity is low. Therefore, we need to pay attention to the selection of materials.

2. Material composition: The more fine powder contained in the material before the jaw crusher, the more it affects sand making, because these fine powders simply adhere to affect transportation. Therefore, materials with high fine powder content should be screened in advance. Select the fine powder from the material as much as possible, so as not to affect the normal operation of the jaw crusher.

3. The fineness of materials after jaw crusher: high fineness requirements, that is, the finer the material from the crusher, the smaller the crushing ability. This aspect depends on the specific requirements. If there is no special requirement, the fineness of the material is generally set to medium fine. Maintenance The jaw plate is the main component of the jaw crusher, and it is also the main vulnerable part. As long as its life is ensured, the service life of the entire equipment is ensured. 　

In the jaw crusher, the dynamic and static jaw plate wear can cause the crusher to fail to operate normally and lose its crushing ability. Ensuring the normality of the jaw plate can ensure the normal production of the jaw crusher, extend the service life of the jaw plate, and reduce wear and tear: 　
　　
The crusher will wear out during the operation. This kind of wear can be reduced but is inevitable. Wear and tear will shorten the life of the machine, so try to reduce it. The crushing machinery itself is also worn out in the process of processing ore. In order to minimize the loss of parts, one is to insist on selecting models scientifically; the other is to use and select materials rationally.
　　
Crushing methods include mixed crushing and pre-screening crushing. Mixed crushing refers to a production process in which two materials in cement production are sent to a crusher according to a certain share. Common mixed crushing includes limestone and marl, limestone and shale, limestone and clay, etc.; the material is sieved before crushing, and only the sieve is crushed, which can *ly improve the crushing efficiency.
