DISINTEGRATOR Russian patent published in 2019 - IPC B02C13/14 

FIELD: disintegrators and crushing devices.

SUBSTANCE: invention relates to grinding various materials and can be used in production of construction materials, as well as in other industries. Device comprises cylindrical housing (1) with axial loading (2) and tangential unloading devices. Vertical disks (4) with rigidly fixed on them rows of impact elements (5), each of which is located between rows of impact elements of the opposite disc, are arranged in housing (1) with possibility of counter rotation. Axial loading device (2) is made in the form of two hollow horizontal screw shafts rigidly connected with disks (4). Each row of impact elements (5) is rigidly and in pairs connected by conical rings (6) symmetrically located relative to vertical axis of housing (1). Large bases of conical rings (6) are directed towards each other, distance between their larger bases on each impact element (5) decreases from inner row to outer from L to (0.1…0.2) L, where L is the length of impact element (5). Outer generating surface of conical rings (6) of previous row of impact elements (5) is conjugated with inner generatrix of conical rings (6) of the next row. Length of sections of overlapping of conic rings (6) of adjacent rows is determined by radial distance between rows of impact elements (5) taking into account process gaps. Axial gap between conical rings (6) of adjacent rows is equal to (2…5)d_max, where d_max is maximum particle size of the ready product. Area of annular gap between larger bases of conical rings (6) of external row of impact elements (5) exceeds total area of cross section of axial loading device (2).

EFFECT: higher efficiency of the grinding process and efficiency of the ready class of the ground material due to selective action on the material.
