Jaw crushers have a long history of development. The jaw crushers produced and designed by our company include PE series jaw crushers, HJ series jaw crushers, and PEW series jaw crushers. They can be used as the primary of the mine crushing industry. Crusher, crushing materials with relatively large volume.

Although the structure of the jaw crusher is different, its working principle is the same, that is, the material is crushed by the periodic reciprocating 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 will be crushed, split and bent. 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, 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.
