A jaw crusher having two jaws which define an upwardly open crushing chamber for receiving crushable material and a discharge opening between the lower ends of the jaws for discharging crushed material, the jaws being relatively movable so as to vary the size of the receiving chamber and thereby exert working and relieving actions on the crushable material and so that crushed material can be discharged via the discharge opening, and in which: a rotatable elongate member extends throughout at least a major part of the length L of the jaws, and is located at or near to the discharge opening so as to assist the gravity discharge of crushed material through the discharge opening, and / or to exert an impact / crushing action in conjunction with the working actions of the jaws. |
