As we touched on above, different jaw crusher designs will operate slightly differently, but how they work is similar across the board. All jaw crushers reduce large sized rocks, ore, or other material by a compression action. A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, “swing” jaw exerts force on the feed material by pushing it

A jaw crusher can crush large rocks very efficiently, but it is not suitable to crush evenly. We deal with many used jaw crushers. In the secondary crushing, the crushed material is hit against the wall to remove the corners to make the grain size uniform. At this stage impact crushers and cone crushers are used.
