In the cone crusher structure, wear often occurs, especially in the lower 1/3, the wear situation is more prominent. The wear of the dynamic and static frontal plates can cause the crusher to fail to operate normally and lose the crushing ability. There will be wear and tear in the crusher during its working process, which can be reduced and unavoidable. Wear will shorten the mechanical life, so try to reduce it. The crushing machinery also has some wear and tear in the process of processing ore. 

In order to minimize the loss of parts, it is necessary to adhere to the scientific selection of models, and rational use and selection of materials. Once the type selection is inappropriate, serious conditions will result in long-term passive production in factories, and light conditions will also result in frequent multi-consumption. The crushing methods are mixed crushing and pre-screening crushing. 

Mixed crushing refers to the production process in which two kinds of raw materials are fed into a crusher in a certain proportion for crushing. Common mixed crushing are limestone and marl, limestone and shale, limestone and clay, etc. Screening raw materials before crushing, only crushing the screening materials, often can achieve good results.
