Working principle of Jaw crusher

The strip and strip pulley are driven by a motor, and the moving jaw moves up and down via eccentric shaft. The angle between fixed jaw and moving jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It will become bigger when the moving jaw runs up. The moving jaw board leaves the fixed jaw board under the action of pole and spring, and then the end products come out from the crushing cavity. And also, Jaw crusher is always used as the Primary jaw crusher.
