ABSTRACT:
A crusher for reducing the size of pieces of rock, concrete and the like is disclosed. A pair of resonant beams are suspended at their upper nodes from the upper end of a frame. The beams are driven by an oscillatory driver which engages the beams near their anti-nodes. A pair of opposed jaws are mounted at the lower ends of the beams and their mutual, reciprocal action applies compressive forces to material fed therebetween which causes the material to break apart. The jaws may be moved apart by a pair of hydraulic cylinders to allow adjustment of the material size discharged from the crusher. The hydraulic system actuating the cylinders is especially adapted to absorb shock imparted by the reactive forces of the jaws against the material being crushed.
