 Jaw crushers have the characteristics of low noise, simple structure, reliable operation, etc., but often due to irregular operation or long-term component wear and other reasons, the discharge does not meet the standard, etc.:

jaw crusher
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 cause a decrease in the output of the entire system and an increase in the internal circulation, which will increase the wear of the crusher. 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 crusher 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-crushing. Then enter the finished product sieve for screening. The whole system is a closed system, which can choose open circuit or closed circuit according to the needs of production.

3. Cycle load
The working process of the jaw crusher is carried out in a closed loop. Adjusting the discharge port and increasing the load in the cycle will improve the shape of the stone material. In the whole process, due to the increase in the cycle load, the equipment in the system 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.
