The lower end of the swing jaw is held in position against the toggle by a spring hold tension rod.The setting of a jaw crusher may be stated as being the close or wide opening between the moving jaw at the outlet end.The reciprocating motion of jaws causes the opening to vary between close and wide, thus crushing takes place in that motion.
