DISINTEGRATOR Russian patent published in 2017 - IPC B02C13/24 B02C13/286 

FIELD: construction.

SUBSTANCE: invention is intended for shredding in the production of building materials and others. The disintegrator contains a housing (1) with the upper (4) and lower (7) horizontal disks with impactors (5, 6, 9). Multistage housing (10) mounted with oscillation ability under the upper disc on axis with the loading device. Multistage rotor (11) with impact beaters mounted on the lower disc on axis with the housing(10). The gap between the housing (10) and the beaters is 2-3 times larger than the maximum particle size. The lower end of the housing (10) is conical form made with radial edges and the angle from the center to the periphery. There is truncated cone (13) with an inclination angle and the radial circumferential grooves at the bottom part of the rotor. Cone base diameter is equal to the outer diameter of the housing (10). Angle greater than the angle of natural slope of the shredding material. Axial hollow loading spout (8) with a screw feeder (15) vertically passes through the lower disc. The upper part of the spout is the bottom stage of the rotor. The side surface of the bottom stage has radial windows (14) between the beaters over the entire height. The upper feeder point coincides with the upper horizontal surface of the lower rotor stage. The gap between the cone generator and the protrusions edges is more than two times larger than the maximum particle size.

EFFECT: device provides shredding efficiency increase.
