DISINTEGRATOR Russian patent published in 2023 - IPC B02C13/14 

FIELD: grinding; mixing.

SUBSTANCE: devices for grinding and mixing various components. 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 impact element 6 and 7 of both horizontal disks is made T-shaped and consists of a vertical cylindrical holder, respectively, 8 and 9 and a radial rectangular plate, respectively, 10 and 11, rigidly fixed to its end, providing process gaps between the profile of each impact element 6, 7 and working surfaces of horizontal discs 4 and 5, as well as between the profiles of impact elements 6, 7 of adjacent rows. The number of impact elements 6 and 7 in a row increases from the center to the periphery of the horizontal disks 4 and 5. The gap between adjacent vertical cylindrical holders 8 and adjacent vertical cylindrical 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. In the center on the lower horizontal disk 5, a collector 12 is rigidly fixed in the form of a conical ring with a large base at the top, in the lower part of the side walls of which through square cutouts 13 are made, the side of which exceeds 2D_max, to the rear walls 14 of which, opposite to the rotation of the lower horizontal disk 5, are adjacent radial rectangular blades 15, on the outer end of each of which a rectangular cutout 16 is made, into which radial rectangular plates 10 of T-shaped impact elements 6 of the inner row enter with a process gap, rigidly fixed on the lower surface of the upper horizontal disk 4.

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.
