What is the reason why the crusher does not meet the standard?

The up and down movement of the crusher can cause extrusion, cracking and bending of the material by prompting the discharge. What is the reason why the crusher does not meet the discharge standards during operation? Here is my compilation:

Crushing ratio

The crushing rate refers to the ratio of the particle size of the imported material to the particle size of the finished product after crushing. The larger the ratio, the greater the breakage rate, and vice versa. For the production process of the crusher, if the crushing rate is large, the needle flake content will increase. Therefore, in production, adjusting the crushing rate is an important measure to ensure the discharge. Of course, if the crushing ratio is too small, it will not work. It will reduce the output of the entire system, increase the internal circulation, and increase the wear of the crusher, so the crushing ratio will increase.

Feed particle size

For crushers, different types or models can process different sizes of feed. And if the feed particle size is not suitable, the output quality will not meet the standard.

Cyclic load

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

Open and closed circuits

In the production of crushers, the cycle is divided into road cycle and closed-circuit cycle. The former is called first screening and then crushing, and the latter is called first crushing and then screening. Which means that the crushed materials enter the secondary crushing entrance before being crushed. First pass the finished product screening, so that the output of the finished material increases, and the needle content also increases.

The above are the reasons why the crusher is not up to the standard. In this case, you can find out the key reasons based on these, I hope it will help you.
