Working Principle of Simple-swing Jaw Crusher

During the working process of jaw crusher machine, movable jaws and fixed jaws form the crushing cavity and this is the major working area. This kind of crusher mainly works on the movement of movable jaws. According to the difference of moving track, jaw crusher is divided into two kinds: simple-swing jaw crusher and compound-swing jaw crusher.

Swing work of movable jaws in simple-swing jaw crusher is relatively simple. Transmission device brings the eccentric shaft to rotate. Connecting bar is installed on the eccentric shaft. Front and behind brackets are connected at the lower end of connecting bar. Movable jaw plates are connected with the end of front bracket.

When eccentric shaft revolves, connecting bar will move up and down. Movable jaws will move front or behind through brackets. When connecting bar moves upward, bracket is forced to move upward and bring the movable jaw plates to approach fixed jaw plates. Raw materials in two jaws are fractured and crushed.

When connecting bar moves downward, movable jaw plates will move behind under the work of spring. The crushed materials are discharged out through discharging mouth under the gravity force. Since this kind of jaw crusher has larger oscillation degree, crushing ratio will be influenced.

Therefore, jaw crusher machine is often used for coarse crushing and secondary crushing of hard rocks. To get the price of jaw crusher machine, you can email us or download it from website directly.
