First of all, what are the components of the jaw crusher structure?

The structure of jaw crusher is relatively simple, mainly composed of frame, working mechanism, transmission mechanism, adjusting device, tensioning device, safety device and lubrication system. The overall structure can be divided into seven blocks;

The working principle of jaw crusher

Although the jaw crusher has various structural types, its working principle is the same, that is, the material is crushed by the periodic motion of the movable jaw. In the process of swinging the movable jaw to the fixed jaw around the suspension mandrel, the material between the two jaw plates is subjected to the combined action of crushing, splitting and bending. At the beginning, the pressure is small, so that the volume of the material is reduced, and the materials are close to each other and squeezed tightly; when the pressure rises beyond the strength that the material can bear, it will break. On the contrary, when the movable jaw leaves the fixed jaw and swings in the opposite direction of the car, the material moves downward by its own weight. Each periodic movement of the movable jaw causes the material to be crushed once and sent down a certain distance. After several cycles, the crushed materials are discharged from the discharge port.
