The principle of jaw crusher is not only friction, but also includes the bite movement of movable jaw and static jaw, as well as the comprehensive effects of material extrusion, splitting and bending.

Jaw crusher, as the leader in crushing equipment, is widely used in mining, building materials, chemical industry and other fields. However, for its working principle, many people may only stay at the level of "friction". Today, let's analyze in depth what the working principle of jaw crusher is.

First of all, the jaw crusher is mainly composed of movable jaw, static jaw and frame. The movable jaw reciprocates on the frame through the eccentric shaft to form a crushing chamber with the static jaw. When the material enters the crushing chamber, the bite movement of the movable jaw and the static jaw begins. In this process, the material is not only subjected to the friction between the movable jaw and the static jaw, but also to the comprehensive effects of strong extrusion, splitting and bending.

The combined result of these forces is that the material is broken into small pieces. And this crushing process cannot be completed by simple friction. Friction is only one of the factors. What is more important is the bite movement of the movable jaw and the static jaw and the movement state of the material in the crushing chamber.

In addition, the working efficiency of the jaw crusher is also closely related to its structural design, motion parameters, and material properties. For example, a reasonable design of the crushing chamber profile can improve the crushing efficiency, while appropriate motion parameters can make the crushing process more stable and reliable.

In general, the working principle of the jaw crusher is far more complicated than we think. It not only involves a variety of mechanical principles such as friction, extrusion, splitting and bending, but is also closely related to the structural design of the equipment, motion parameters, and material properties. Therefore, when using the jaw crusher, we need to fully understand its working principle in order to better exert its performance and improve production efficiency.
