Abstract: A blade plate for a crusher, where in the blade plate is normally installed on a fixed side or a movable side, includes a base material part, and a large number of blade parts arranged on a surface of the base material part. The blade parts include a rhombic blade part that forms a rhombic blade at a corner between inclined portions and a mountain-shaped blade part that is formed in a polyhedron shape in which a cross-shaped tip blade is formed at a corner between chipped portions provided at inclined portions. An inclined blade is formed at a corner between the inclined portions and is coupled to the rhombic blade part at an intersection point of diagonals of the rhombic blade part and a crusher using the blade plate.

Abstract: A blade plate for crushers to be installed on a fixed side or a moving side, includes a base material part and many blade parts arranged on the surface of the base material part. The blade part includes a diamond blade part having an edge formed of a corner between a belt-like part and an inclined part, and a chevron blade part which is configured in a polyhedral shape having an edge formed of a corner between a cross-shaped tip end belt-like part and a foot part and an edge formed of a corner between an inclined belt-like part and a foot part, and which is bound to an intersection place of the diagonal lines of the diamond blade part. Also provided is a crusher which utilizes the blade plate.

Abstract: An apparatus for shearing and breaking nonferrous castings of the present invention includes a first cutter unit and a second cutter unit disposed in a frame. Each of the first cutter unit and the second cutter unit includes at least an intermediate cutter unit located at the intermediate stage and a lower cutter unit located at the lower stage. Each of the intermediate cutter units is a multi-vertex cutter part formed into a multi-vertex shape by rhombic cutting edges and crucial cutting edges connected to the respective intersections of diagonals of the rhombic cutting edges. The lower cutter units respectively have a concave cutting edge and a convex cutting edge which are engaged with a gap being formed therebetween.

Abstract: The present invention is a method for making aluminum scrap into a product furnished with a trimming apparatus equipped with a pair of dies and cutters for cutting aluminum waste from an aluminum product held by a chuck, and a shearing apparatus provided with one cutting formation equipped with half-cut pyramid-shaped cutters and another cutting formation equipped with half-cut pyramid-shaped cutters facing the one cutting formation fitted to a frame equipped with an input opening for inputting aluminum scrap provided at a lower position and a discharge opening for discharging aluminum product raw material. Aluminum scrap cut by the trimming apparatus can be crushed or sheared to dimensions taken as aluminum product raw material utilized in shearing apparatus. As a result, the aluminum waste is cut from the aluminum casting completely automatically, and the cut aluminum waste can be adopted as aluminum product raw material.
