Abstract: The present invention provides an industrial waste cutting apparatus for cutting finely the industrial wastes generated from such as industrial products of a great variety of types and domestic products such as used materials and old furniture, regardless of whether they are soft or hard, so that they can be easily disposed off, and it is an object thereof to cut soft materials, which are especially difficult to cut, with a very high efficiency.

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.

Abstract: A crushing machine for crushing such as concrete structural members of buildings includes: a crushing machine outer casing; a fixed jaw body provided fixedly on the crushing machine outer casing; and a movable jaw body provided movably on the crushing machine outer casing to effect an opening and closing operation in cooperation with the fixed jaw body; wherein a crushing blade formed substantially in a shape of a semicircular cutting blade is provided at a distal end of the movable jaw body. The crushing blade includes a rear-side edge which is formed in a substantially right-angled shape with a small arcuate edge portion located at an angled portion thereof and a front-side edge which as a whole is generally formed by a large arcuate edge portion. The rear-side edge is located at a position closer to a longitudinally inward direction side of the movable jaw body relative to the front-side edge.
