Jaw crusher is mainly used for rough crushing of stone materials, and it is one of the commonly used crushers. It is the first crushing equipment in stone production line and sand production line. The production capacity of jaw crusher determines the production efficiency of the whole production line. So, what are the factors that affect the output of jaw crusher?
* Material hardness
The higher the hardness of the raw materials broken by the jaw crusher, the more difficult the crushing is, and the more serious the wear of the two jaw plates and other components of the equipment. As a result, the speed and capacity of crushing are reduced. Therefore, in the crushing operation, we need to pay attention to the choice of moderate hardness of stone materials for crushing.
* The material contains fine powder
The more fine powder contained before the material is broken, the greater the impact on the output of finished products. Because these fine powder is easy to adhere to affect the transportation, leading to the reduction of the production capacity of jaw crusher. On the other hand, fine powder cannot be used as finished stone, reducing the overall output of finished stone. It is suggested that the material with high fine powder should be screened in advance, and fine powder should be screened from the material as far as possible, so as to avoid affecting the normal production of jaw crusher.
* Material humidity and viscosity
The moisture content in the material is large, which will increase the viscosity of the material accordingly, so that it is easy to adhere to the wall of the crusher. If the cleaning is not timely, the high viscosity materials attached to the inner wall of these crushers will affect the stone crushing efficiency of the jaw crusher. In the selection of crushing materials, according to the working parameters of jaw crusher, select suitable materials with viscosity and water content.
* Discharging particle size
The fineness requirement is high, that is, the finer the particle size of the finished product, the smaller the stone output of jaw crusher, which depends on the specific production requirements of the user. If the user has no special requirements on the granularity of finished products, it is recommended to set the fineness to medium fine when crushing materials.
* Eccentric shaft speed
The speed of eccentric shaft affects the production capacity of jaw crusher. The production capacity of jaw crusher will increase with the increase of the speed of the eccentric shaft. When the speed reaches a certain value, the production capacity of the jaw crusher is the largest. Since then, the rotational speed increases again, the production capacity decreases sharply, and the content of overcrushed products also increases.
