wear problem associated with single toggle jaw crushers. Lindqvist and Evertssonused a small jaw crusher to [14] study the wear of the crusher liners for different settings of the crusher. In this work, the authors measured the crushing forces and tracked the motion of the crusher along with the wear on the crusher.
Jaw crushers typically use the principles of compression and friction to break materials down. They're extremely powerful equipment that should be used with the utmost care. Jaw crushers are so powerful that they've earned the moniker "rock breakers" because of their brute force. All jaw crushers will have one fixed jaw and a moving one.
