Jaw Crushers Working Principle
Jaw crusher is 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 plate leaves the fixed jaw plate under the action of pole and spring, and then the end products come out from the crushing cavity. And also, Jaw crusher is used as both Primary jaw crusher and Secondary jaw crusher.
