How Does a Jaw Crusher Work? A Simple Guide
In jaw crushers, the crushing force is generated by the movement of the movable jaw plate towards the fixed jaw plate. This force is a result of the mechanical pressure created by the eccentric shaft and transmitted through the toggle plate. The interesting thing is how these forces are applied to the material.
