DISINTEGRATOR Russian patent published in 2017 - IPC B02C13/22 

FIELD: machine engineering.

SUBSTANCE: disintegrator comprises a cylindrical casing 1 with axial 3 loading and tangential 2 unloading devices. In the housing 1 to counter-rotating upper 4 and lower horizontal discs 7 rigidly attached thereto in concentric circles row of impact elements 5, 6 and 9 are arranged. Each series of impact elements is located between rows of impact elements of the opposite drive. The distances between the impact elements are reduced from the center to the periphery of the discs 4 and 7. Disks 4 and 7 are made of different diameters. Symmetrically placed vertical supports 11 are rigidly attached to the end of the largest 4 disc, which accomodates the penultimate row of the impact elements 6 of the grinding chamber. Conical rings 12 with concentric projections and grooves are rigidly fixed over their entire height to the outer surface of the outer row of the impact elements 9 and to the inner surface of the vertical supports 11. The conical rings 12 of the upper 4 and lower 7 discs are arranged vertically one-by-one. Tilt angle α of each conical ring 12 generator exceeds the angle of the natural slope of the material. Between the concentric grooves and the protrusions of adjacent conical rings 12, a gap is formed. The gap has a size (2-10) d_max, where d_max is the maximum particle size of the finished product. The height of the vertical supports 11 exceeds the height of the impact elements 9.

EFFECT: increased efficiency of desintegrating process.
