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: 　
　
1, crushing ratio
The crushing ratio refers to the ratio of the imported material to the particle size of the finished product after crushing. The larger the ratio, the larger the crushing ratio, and vice versa. For the production process of the jaw crusher, the larger the crushing ratio is, the pin flake content Therefore, in production, the adjustment of the crushing ratio is an important measure to ensure the discharge. Of course, too small a crushing ratio will not work. This will reduce the output of the entire system and increase the internal circulation, which will increase the wear of the crusher, so the crushing The choice of ratio needs to be appropriate. 　　

2, open and closed loop
In the production of the crusher, there is a separate cycle and a closed cycle. The former is called sieving and then crushing, and the latter is called sieving and then sieving. First sieving and then smashing means that the crushed material is * screened through the finished product sieve. Then enter the secondary crushing feed inlet for crushing, so that the output of the finished material increases, and the needle-like content also increases. The * crushing and then the screening means that all the crushed materials enter the secondary crusher feed inlet for re-breaking. Then enter the finished product sieve for screening. The whole system is a closed system, which can be selected according to the production needs of open circuit or closed circuit.

3, cyclic load
The working process of the jaw crusher is carried out in a closed loop. When the discharge port is enlarged and the load in the loop is increased, the shape of the stone material will become better. However, when the discharge port is enlarged, the load of the main crushing motor can be reduced, and the finished material will be better deformed. Therefore, in the production, the adjustment of the cyclic load is very important. 　
　
4, feed size 　　
For jaw crushers, different types or different models can be processed with different feed sizes. If the feed size is not appropriate, the quality of the output will not meet the standard.
