FIELD: machine building.SUBSTANCE: disintegrator comprises a cylindrical casing with axial loading and tangential unloading branch pipes. In the cylindrical casing, top and bottom horizontal disks are installed with the possibility of counter-rotating, they have impact elements secured along the concentric circles, each is located between impact elements of the opposite disk. Spreading branch pipes are arranged at axial loading pipe outlet at the angle to the top horizontal disk. The inclination angle of the spreading branch pipes to the upper horizontal disk is greater than the angle of natural slope of the material. Device for material uniform distribution over the working chamber perimeter is arranged at the bottom horizontal disk under spreading branch pipes. A cylindrical deflector is rigidly attached to the first inner row of the impact elements on the side of the spreading branch pipes. A cylinder with vertically set impact hammers is rigidly attached to the lower edge of the spreading branch pipes. The lower point of the cylindrical deflector is located at the intersection of its working surface and the straight generatrix laid on the inner surface of the spreading branch pipe. The upper point of the cylindrical deflector is located above the upper point of the spreading branch pipe cross section. The distance between the spreading branch pipe cross section and the cylindrical deflector lining is equal to 2-3d. The distance between the radius of a circumscribed circle of the impact hammers and the inner radius of the first inner row of impact elements exceeds d, where dis the maximal size of a particle of the material being crushed.EFFECT: disintegrator allows for significant intensification of crushing process.2 dwg |
