ABSTRACT:
A jaw crusher is disclosed wherein opposed jaws converge downwardly to form a passage for material to be crushed, the jaws being supported on a frame structure by resilient floating mounts connected in series with each other and between the respective jaws and the frame structure. Each resilient floating mount preferably includes a wheel and pneumatic tire arranged coaxially within a relatively larger cylindrical track. Balanced eccentric masses are supported on each jaw for uniformly driving them in oscillatory vibration. The jaws are configured so that when lower portions of the jaws are generally parallel in order to achieve fine crushing, the upper jaw portions form a converging angle of approximately seven to sixteen degrees in order to achieve enhanced crushing particularly in combination with the balanced eccentric masses and the series connected resilient floating mounts.
