For the production process of the jaw crusher, whether it is the occurrence of failure, the analysis of the cause of the output decline, or the solution of the unreasonable discharge phenomenon, they are all important operations in the production. These operations are all to ensure Different phenomena are caused by different reasons for the benefits of production. Here are the reasons for the non-compliance phenomenon from the following four points.
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 needle-like 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. 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 feed will not meet the standard.
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. Open and closed loop
In the production of jaw crushers, there are separate circulation and closed circulation. The former is called sieving before crushing, and the latter is called crushing and then sieving. Screening before crushing means that the crushed material is passed through the finished sieve. After screening, 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 first crushing and then the screening means that all the crushed materials enter the secondary jaw crusher feed inlet , After re-breaking, 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.
