Jaw crusher is one of the most common crushing equipment, which mainly depends on the interaction of the swing jaw plate and the fixed jaw plate to achieve the material crushing. Therefore, the jaw plates are the main working parts. If the jaw plates are broken, the whole equipment will be not run normally and lose the crushing capacity. However, the jaw plates have huge workload, which are the main wearing parts. So, to ensure the service life of the equipment, we will minimize the jaw plate wear to extend its service life. How to extend the service life of jaw plate? Believe that this is the most concern for users during application of jaw crusher. The specific methods are as follows:
1. Crusher will be worn in the process of work, which can be reduced but inevitable. The wear will shorten its service life, so the wear should be reduced as much as possible. The machine itself is also wear during ore processing. In order to reduce the wastage of the parts, one hand scientifically choose models, another hand rational use and material selection.
2. There are two crushing ways includng mixed and pre-screening. The mixed crushing refers to one manufacturing technique that two kinds of raw material base on certain proportion enter into crusher in the process of cement production. The common mixed crushing has limestone and marl, limestone and shale and limestone and clay, etc.The pre-screening shall be done before crushing material, then only crush the oversize material, in this way we can reduce the wears, and meantime obtain good crushing effect.
