Working Principles of jaw crusher:
The motor drives the belts and the belt wheels, and make the movable jaw up and down by the eccentric shaft. When the movable jaw descends, the angle between the fixed jaw and the movable jaw becomes smaller, and the materials can be crushed; when the movable jaw rises, the angle between the fixed jaw and the movable jaw becomes bigger; and the movable jaw plate leaves from the fixed jaw by the function of the tension rod and the spring. And then the crushed materials are discharged from the lower outlet of the crushing cavity.
