When the toggle plate is destroyed, the movable jaw cannot move on routine track and the whole machine has to break down. Toggle plate shims are used to prevent toggle plate from abrading the machine directly. If they are worn out, the toggle plate will impact the body of main frame and the body of movable jaw. As a result, the service-life of the two parts will be affected. Click to know about double toggle jaw crusher and single toggle jaw crusher.
