Reasons for the unqualified discharge of mobile crushing plant

For the production process of mobile crushing plant, whether it's the cause of failure, the cause analysis of production decline, or the solution of unreasonable discharge, are all important operations in production. These operations are to ensure the production efficiency. The cause analysis of non-compliance is caused by different reasons. Here is to introduce the problem of discharge failure What causes the phenomenon of reaching the standard.

Crushing ratio

The crushing ratio refers to the ratio of 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 crushing plant, if the crushing ratio is large, the content of needle and flake will increase. Therefore, the adjustment of crushing ratio is an important measure to ensure the discharge of material. Of course, if the crushing ratio is too small, it will cause the output of the whole system to drop With the increase of internal circulation, the wear of crusher increases, so the selection of crushing ratio needs to be appropriate;

Feed particle size

For the crusher, different types or models can process different sizes of feed. If the feed size is not appropriate, it will also cause the phenomenon of substandard discharge quality. For example, when the feed size is reduced from 100 mm to 50 mm, the content of needle and flake in the finished product decreases by 38%, so the feed size must meet the requirements of production equipment;

Circulating load of mobile crushing plant

The working process of the crusher is carried out in a closed-circuit cycle. Adjust the discharge port to increase the load in the cycle, and the stone particle shape will be better. In the whole process, due to the increase of the cycle load, the wear of the equipment in the system will increase. However, when the discharge port is larger, the load of the main crusher can be reduced, and the deformation of the finished product particle is good. Therefore, in the production, adjust the cycle load The whole is very important;

Open circuit and closed circuit

In the production of the crusher, the circulation is divided into circulation and closed circulation. The former is called first screening and then crushing, the latter is called first crushing and then screening. First screening and then crushing refers to the crushing of the material after the first stage crushing through the finished product screening and then entering the second stage crushing feed port. In this way, the output of the finished material increases, and the content of needle and sheet also increases. First crushing and then screening refers to the feeding of all the first stage crushing materials Enter the feed inlet of the secondary crusher, and then enter the finished product screen for screening after re breaking. The whole system is a closed system, without loss of crushing materials, but the product has a good particle shape. In the actual production of the crusher, the discharge of the mobile crushing plant can be selected according to the production demand for open circuit or closed-circuit circulation.
