DISINTEGRATOR Russian patent published in 2020 - IPC B02C13/22 

FIELD: disintegrators and crushing devices.

SUBSTANCE: invention relates to the various materials crushing devices and may be used in production of construction materials and other industries. Disintegrator comprises cylindrical housing 1 with axial 2 loading and tangential 3 unloading devices. Discs 4 and 5 are arranged in cylindrical housing 1 to counter-rotate, with rows of impact elements 6 and 7, respectively, each of which is located between rows of striking elements of opposite disc. To lower ends of internal row of impact elements 6 of upper disc 4 horizontal ring 8 is rigidly attached. Vertical shaft 9 is rigidly fixed on lower disc 5 and passes with process clearance through hole in center of horizontal ring 8. Spreading blades 10 symmetrically arranged in plan are rigidly fixed on vertical shaft 9. Between spreading blades 10 and horizontal ring 8 there is a process gap. On upper surface of horizontal ring 8 along concentric circle vertical baffles 11 symmetrically located in plan are fixed, number of which is not less than number of spreading blades 10. Each of vertical baffle plates 11 has radial width equal to (0.2…1.0)D_max, where D_max is maximum size of particles of ground material. Inner end of each spreading blade 10 is inclined to center of horizontal ring 8 with upper edge located on radius equal to inner radius of loading device 2 and with vertical clearance from it, larger D_max. Outer face of every spreading blade 10 is provided with process clearance to inner row of impact elements 6. Spreading blades 10 have through cutouts 12 corresponding to lateral profile of vertical baffle plates 11 with provision of process clearance. Radial gap between vertical baffle plates 11 and impact elements 6 of inner row is more than D_max.

EFFECT: disintegrator increases efficiency of the grinding process and productivity of the finished product due to increased number of collisions of particles.
