ABSTRACT:
A crushing machine having enhanced crushing efficiency. The crushing machine includes an outer casing having a fixed jaw and a movable jaw each having a crushing blade for crushing reinforced concrete. The movable jaw includes a crushing blade having a rear-side edge formed in a substantially right-angled shape with a small arcuate edge portion located at an angled edge portion thereof, and a front-side edge generally formed by a large arcuate edge portion. The rear-side edge of the movable jaw crushing blade is oriented to face in a longitudinally inward direction away from a distal end of the movable jaw. The inward orientation of the rear-side edge along with its substantially right-angled shape allow the movable jaw crushing blade to concentrate the load of the crushing machine to the small point of contact between the movable jaw crushing blade and the reinforced concrete, thereby maximizing the crushing efficiency of the crushing machine. The shape and orientation of the movable jaw crushing blade of the present invention also allows the blade to bite into the concrete, thereby preventing slippage between the blade and the concrete.
