Jaw crusher in mining, building materials, infrastructure and other industries are mainly used for coarse and medium crushing, with a large crushing ratio, high output, simple structure, uniform crushing size, simple maintenance and other characteristics. Below we mainly introduce several key parts of the jaw crusher.

Jaw crusher

1. Move and fix the jaw plate
   The jaw plate is the part that directly contacts with the material when the jaw crusher is working. In the process of the jaw crusher, the material is constantly squeezed and ground in the crushing chamber formed by the dynamic and fixed jaw plate to complete the crushing.
2. Elbow plate
   Elbow plate is also known as the thrust plate, although it is simple, but has a very important role. The elbow plate can transmit power, which is used to support the lower end of the moving jaw to swing, and is also the safety device of the jaw crusher. When the crushing chamber enters the refractory material, the elbow plate breaks first, and then protects the valuable parts of the machine (such as the moving jaw, the body, etc.) from damage.
   3, adjust the device
   The adjustment device in the jaw crusher is used to adjust the size of the crusher’s discharge port, the jaw crusher has a variety of adjustment methods such as wedge type, gasket type and hydraulic type, commonly used wedge adjustment method, composed of two wedges before and after, the front and back wedges can move, change the distance between the two, and then adjust the size of the discharge port, simple and quick, and such adjustment is very casual. It saves time and reduces downtime.
3. Flywheel
   Flywheel is also an important part of the jaw crusher, flywheel in the jaw crusher work has two important roles, one is to balance the weight of the groove wheel, the second is to store energy. Because the jaw crusher is intermittent work, divided into working stroke and idling stroke, resulting in the motor load is extremely unbalanced, in order to balance the motor load, it is necessary to store the energy of the idling stroke when the moving jaw leaves the static jaw, so as to release all the energy in the working stroke.
