Jaw Crusher A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward untilJaw Crusher small enough to escape from the bottom opening. The movement of the jaw can be quite small, since complete crushing is not performed in one stroke. http://www.break-day.com/en/images/2.jpg
