Abstract: A jaw crusher unit for use in crushing stone and other crushable material has a fixed jaw and a movable jaw which define a crushing zone therebetween. A drive mechanism coupled with the movable jaw operates to rock the movable jaw to and fro to crush material in the crushing zone. A link mechanism sets a space between the lower end of the movable jaw and the fixed jaw and thereby controls the discharge of crushed material from the lower end of the crushing zone. A removable wear plate is mounted on a mounting face of at least one of the jaws by a wedge arrangement coupled with a power-operated linear actuator. The linear actuator moves the wear place into and out of engagement with the mounting face to facilitate replacement of the wear plate.
