Jaw crusher unit

摘要

A jaw crusher unit for use in crushing stone and other crushable material having a fixed jaw and a movable jaw which define a crushing zone therebetween. A drive mechanism coupled with the movable jaw is operative to rock the movable jaw to and fro in order to crush material in the crushing zone. A link mechanism connected to a lower end of the movable jaw serves to set any required space between the lower end of the movable jaw and thereby control the discharge of crushed material from the lower end of the crushing zone. The link mechanism includes a pressure-medium controlled toggle mechanism which is automatically adjustable to compensate for wear.
