The up and down movement of the stone crusher can cause the material to extrude, crack and bend by promoting the unloading. During operation, what is the reason for the unqualified discharge of the crusher?

1. Crushing ratio

Crushing rate refers to the ratio of the particle size of imported materials to the particle size of finished products after crushing. The greater the ratio, the greater the crushing rate, and vice versa. For the production process of the stone crusher, if the crushing rate is large, the needle and flake content will increase. Therefore, in production, adjusting the crushing rate is an important measure to ensure discharging. Of course, if the crushing ratio is too small, it will not work, which will reduce the output of the whole system and increase internal circulation, and increase the wear of the crusher, so the crushing ratio will increase.

2. Feeding size

For stone crushers, different types or models can process different sizes of feed. If the feeding size is not appropriate, the output quality will not reach the standard.

3. Cyclic load

The working process of the stone crusher is closed loop. If the outlet is enlarged and the load in the circuit is increased, the shape of the stone particles will become better. In the whole process, due to the increase of cyclic load, the wear of equipment in the system will also increase. However, when the outlet is expanded, the load of the main crushing motor will be reduced, and the finished particles will be well deformed. Therefore, it is very important to adjust the cyclic load in production.

4. Open circuit and closed circuit

In the production of stone crusher, circulation is divided into open circulation and closed circulation. The former is called screening before crushing, and the latter is called crushing before screening. It means that the crushed materials pass through the finished product screening before entering the secondary crushing inlet for crushing, so that the output of finished materials increases and the needle content also increases.

The above are the reasons for the unqualified discharge during the operation of the stone crusher. In this case, we can find out the key reasons based on these, and hope it will be helpful to you.
