PURPOSE:To crush a material to be crushed without feeding water into a hopper and to efficiently discharge a crushed material by centrifugal force by making each edge of plural fixed blades adjustable in the radial direction toward the center of a cylindrical casing. CONSTITUTION:Plural fixed blades 18 which are formed projectingly on the inner periphery of a cylindrical casing 14 at regular intervals and whose each edge is made adjustable in the radial direction toward the center of the cylindrical casing 14, and a fixed disk 24 which is installed in the cylindrical casing 14 keeping a desired clearance from its inner peripheral surface are provided. Rotating blades which are arranged on the fixed disk 24 so as to extend at a fixed angle in the radial direction and integrally fixed to a central boss and fixed to a driving shaft 28a of a driving motor 28 passing through a central through hole 24a of the fixed disk 24 from below to above and whose plural blades 22 are each integrally provided with a blade are attached. Further, a circular discharge port 30b formed in a desired place in the inner periphery of a cylindrical discharge chamber and a circular dust chute 32 connected to it are formed. |
