The cone crusher is a crushing device commonly used in production. Spindle breaks are a common type of failure during production runs. Frequent breaks in the spindle not only affect normal production, but also aggravate routine maintenance and overhaul work. For this fault, this paper analyzes the cause of the fault and finds a solution. A detailed analysis of the causes of the main shaft fracture and the solutions are as follows.
 

 The jaw crusher is also a jaw crusher, referred to as E-breaker. It is mainly used for medium-size crushing of various ores and bulk materials. It is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The highest compressive strength of the material to be crushed is 320 MPa. So what are the reasons for the temperature rise of the jaw crusher?
 

 The cone crusher is mainly divided into upper and lower parts, of which we call it “upper cavity”, which is mainly broken according to the principle of material layer, and the bottom is “lower cavity”. According to the different crushing chambers of the cone crusher, it can be generally divided into three types: medium crushing, medium fine crushing and fine crushing. In the selection process, it is necessary to take into account the specifications of the finished product that the customer needs. Of course, the cone machine produced by the relatively mature cone crusher manufacturer can be fine-tuned to meet the customer's needs. Different needs.
 

 The new type of smashing is a new type of high-efficiency crushing equipment developed in recent years. It is widely used in the coarse and medium crushing of various hard rock, and it also adds dustproof device to meet the production needs of the times. And the muffler device can effectively reduce the pollution caused by the smashing in the operation and the threat to the health of the operator. The new smashing in the market can create higher profits for the customer's production, then the new smashed What are the advantages? Here we come to answer the customer one by one.
 

 The jaw of the jaw crusher is one of the wearing parts. The wear of the jaw plate brings a lot of maintenance work, which not only consumes time and labor, but also seriously affects the production and reduces the economic benefits of the enterprise. Let's take a look at how to reduce the wear and tear of the jaw crusher and extend its service life.
