DISINTEGRATOR Russian patent published in 2023 - IPC B02C13/14 

FIELD: construction.

SUBSTANCE: invention relates to devices for grinding and mixing various components and can be used in the production of building materials. The disintegrator contains cylindrical body 1 with axial loading device 2 and tangential unloading device 3. In cylindrical body 1, disks 4 and 5 are placed and adapted for counter rotation, with rows of impact elements 6 and 7 rigidly fixed on them, each of which is located between the rows of impact elements of the opposite disk. Each T-shaped impact element 6 and 7 of both disks consists of a vertical holder, respectively, 8 and 9, and a radial rectangular plate, respectively, 10 and 11, rigidly fixed to its end, providing vertical clearances, respectively, between the horizontal ends of radial rectangular plate 10 and 11 and the horizontal working surface of opposite disk 5 and 4, as well as between the horizontal ends of radial rectangular plate 10 and 11 of the adjacent row, and the radial clearances between the side ends of radial rectangular plate 10 and 11 and the side surface of vertical holder 8 and 9 of the adjacent row, whereas the number of vertical holders 8 and 9 in a row increases from the center to the periphery of disks 4 and 5, and the gap between adjacent holders 8 and adjacent holders 9 in a row decreases from (2-3) D_max to (1-2) D_max, where D_max is the maximum particle size of the crushed material, whereas paddle spreader 12 is rigidly fixed in the center of the upper surface of lower horizontal disk 5, the radial distance from the outer ends of which to the inner ends of the nearest row of radial rectangular plates 10 exceeds 2D_max.

EFFECT: increased efficiency of grinding and mixing due to the intensive movement of particles of various components in the peripheral zone of the working chamber.
