· 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.

A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.

Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.
