The working principle of the jaw crusher : the motor drives the belt and the pulley, and moves the upper and lower movements through the eccentric shaft. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw. At the same time, the material is crushed or chopped to achieve the purpose of crushing; when the moving down, the angle between the toggle plate and the moving jaw becomes smaller, and the moving jaw is separated from the fixed jaw by the action of the pull rod and the spring. The broken material is discharged from the lower opening of the crushing chamber. As the motor rotates continuously, the crushing motor is used to periodically crush and discharge the material to achieve mass production. The performance advantages of the jaw crusher are shown in the following aspects: 1. The crushing chamber is deep and has no dead zone, which improves the feeding capacity and output; the crushing ratio is large, and the product granularity is uniform; 2. The gasket type discharge port adjusting device is reliable and convenient, and the adjustment range is large, which increases the flexibility of the device; 3. The lubrication system is safe and reliable, the parts are easy to replace, the maintenance workload is small, the structure is simple, the work is reliable, and the operating cost is low. 4. Equipment energy saving: single machine energy saving 15% ~ 30%, system energy saving more than double; discharge opening adjustment range is large, can meet the requirements of different users; low noise, less dust. The jaw crusher uses a hydraulic safety device that is reliable and safe, and easy to troubleshoot. Large and medium-sized crushers generally use sliding bearings cast with babbitt, which can withstand large impact loads and are relatively wear-resistant. The small jaw crusher uses rolling bearings, which has high transmission efficiency and convenient maintenance.

Jaw crusher appeared in 1858, though it is an ancient crushing equipment, but because of its simple structure, reliable, easy to manufacture, easy maintenance, etc., still metallurgical mining, building materials, chemicals and railways and other departments widely used. In mines, it is mostly used for coarse and medium crushing of hard or medium hard ore.
