The rotor recess 25 is formed on the outer peripheral surface 21 of the rotor 20 composed of a plurality of disks so as to be turned forward in the rotor radial direction R so that the blade edge 16 has a rake angle α. The action of shearing, tearing, and cutting is enhanced, and the impact when the blade body 15 acts on the object to be crushed is firmly received by the rotor 20. The blade holder 10 has the same width as the rotor disk width, and is further turned forward in the rotor radial direction R so that the blade edge 16 has an optimum rake angle α with respect to the crushed object. The blade holding recess 12 is formed. In order to firmly attach the blade holder 10 to the rotor recess 25, a counterbore 13 corresponding to the screw hole 26 of the rotor recess 25 is formed so that the head of the bolt B1 does not go outside. A jack screw hole (not shown) for removal is also formed. Further, the blade holder 10 is provided with a blade outer peripheral portion recess 25 for the blade holder.
Blade holding recess 1 of the outer surface opposite to the bottom surface portion to be fitted with
2 is formed in an inclined state such that the distance from the rotary axis becomes shorter toward the rear side of the rotation, and the crushed material can be smoothly moved to the rear of the blade body 15 to be efficient. The crushing work can be carried out.

The blade holding recess 12 of the blade holding body 10 is formed in a rectangular shape with respect to the polygonal blade body 15 and in an arc shape with respect to the circular blade body 15, so that the blade body 15 is settled down. I'm doing better. The blade body 15 has a typical square shape shown in FIG. 3A and FIG. 8A, and FIG. 3B and FIG.
Hexagonal shape shown in (b), FIGS. 3 (c) and 8
(C), and the like, the former having a polygonal edge 16 having two polygonal edges, can be used even if it is turned over, and an edge having twice the number of corners can be used. The blade 15 made of a material can be used more effectively. The latter round shape also has a circular edge 16 on the front and back, and the effective use of the edge is greater than that of the polygonal shape, and the cut is sharper. Further, the manufacturing cost of the crushing blade 1 is low, and the maintenance becomes easy. Each blade body 15 has counterbore holes 17 for fixing bolts on the front and back.

As shown in FIG. 4, the arrangement of the crushing blades 1 with respect to the rotor 20 is such that those that are easily crushed are linearly arranged in the same phase in the rotor width direction so as to crush all crushable ones at once, or the crushing load is simultaneously increased. As shown in FIG. 5, the rotor 20 is symmetrically arranged from the center in the width direction so as not to cover the rotor 20 and to be arranged in a phase shifted manner with respect to the rotor 20 adjacent to the rotor 20 in the width direction so that the load on the rotor 20 is well balanced and smooth crushing can be performed. And those obliquely arranged as shown in FIG. In each arrangement, the blade body 15 is set in a state where adjacent ones in the width direction of the groove overlap or have no gap.
Can be projected slightly to the left and right.
