What is the working principle of jaw crushers?
The commonly used jaw crusher has two kinds of double elbow plate and single elbow plate. In the former, the movable jaw is only used as a simple circular arc oscillation, so it is also called a simple swinging jaw crusher. The latter moves up and down while swinging the circular arc, so it is also called the complex swinging jaw crusher.
In addition, in order to meet the requirements of different particle sizes and compensate the wear of the jaw plate, an adjusting device for the discharge port is added. The adjusting shim or wedge is usually arranged between the elbow plate seat and the back frame. But in order to avoid the replacement of broken parts and affect production, but also the use of hydraulic devices to achieve insurance and adjustment. Some jaw crusher also directly hydraulic drive to drive jaw plate, in order to complete the material crushing action. These two types of jaw crushers using hydraulic transmission are often referred to as hydraulic jaw crushers.
Jaw crusher work principle is: use two jaw board to material extrusion and bending function, coarse, broken or medium, break all kinds of hardness material.The crushing mechanism is composed of a fixed jaw plate and a movable jaw plate, and when the two jaw plate approaches, the material is broken, and when the two jaw plate leaves, the material block smaller than the discharge opening is discharged at the bottom. Its crushing action is intermittent. Because of its advantages such as simple structure, reliable operation and the ability to crush hard materials, the crusher is widely used in industrial sectors such as ore dressing, building materials, silicates and ceramics.
