What factors affect the output of jaw crusher?
Jaw crushers are mainly used for coarse crushing of materials. They are one of the commonly used crushers. They are the first crushing equipment in stone production lines and sand production lines. The production capacity of jaw crushers determines the production efficiency of the entire production line. So, what are the factors that affect the output of jaw crusher?
1. Material hardness
The higher the hardness of the raw material crushed by the jaw crusher, the more difficult it is to crush, and the more serious the wear on the two jaws of the equipment and other components. As a result, the speed of crushing becomes slower and the capacity decreases. Therefore, during the crushing operation, I need to pay attention to choosing rubble materials with moderate hardness for crushing.
2. The amount of fine powder contained in the material
The more fine powder the material contains before crushing, the greater the impact on the output of finished products, because these fine powders are easy to adhere and affect the transportation, resulting in a reduction in the production capacity of the jaw crusher. On the other hand, fine powder cannot be used as finished stones. Use the same to reduce the overall output of finished stone products. It is recommended that materials with high fine particle content should be screened once in advance, and fine powder should be screened out from the material as much as possible to avoid affecting the normal production of the jaw crusher.
3. Material humidity and viscosity
The high moisture content in the material will increase the viscosity of the material accordingly, making it easy to adhere to the inner wall of the crusher. If it is not cleaned in time, the high-viscosity materials attached to the inner wall of these crushers will affect the stone-breaking efficiency of the jaw crusher. When selecting crushed materials, according to the working parameters of the jaw crusher, select materials with appropriate viscosity and water content.
4. Discharge particle size
The requirement for fineness is high, that is, the finer the particle size of the material required for the crushed product, the smaller the stone output of the jaw crusher, which depends on the specific production requirements of the user. If the user has no special requirements on the particle size of the finished product, it is recommended to set the fineness to medium fine when crushing materials.
5. Speed of eccentric shaft
The speed of the eccentric shaft affects the production capacity of the jaw crusher. The production capacity of the jaw crusher will increase with the increase of the rotational speed of the eccentric shaft. When the rotational speed reaches a certain value, the production capacity of the machine will be maximum. After that, the rotating speed increases again, the production capacity drops sharply, and the content of over-grinded products also increases.
