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 contains cylindrical housing 1 with axial loading 2 and tangential unloading 3 devices. In housing 1 disks 4 and 5 with rows of impact elements 6 and 7 are installed with the possibility of opposite rotation, each of which is located between rows of striking elements of the opposite disk. Upper 8 and lower 9 horizontal rings are rigidly attached to lower ends and to middle part of inner row of impact elements 6 of upper disk 4. Axial loading device 2 includes rigidly attached to disks 4 and 5 upper hollow loading branch pipe 10 and lower hollow screw tube 11 passing with process gap through hole in center of lower horizontal ring 9. Lower spreading blades 12 are rigidly attached to upper end of screw tube 11, and there is a process gap between them and lower horizontal ring 9. On upper surface of upper 8 and lower 9 horizontal rings along concentric circle vertical baffles 13 and 14 are fixed, respectively, each of which has radial width not exceeding D_max, where D_max is maximum size of particles of ground material. Vertical shaft 15 is rigidly attached to upper ends of lower spreading blades 12, passing with process gap through upper horizontal ring 8. Top spreading blades 16 are rigidly attached to vertical shaft 15 with vertical clearance from loading branch pipe 10 exceeding D_max. External ends of upper 16 and lower 12 spreading blades are provided with process clearance to inner row of impact elements 6. Upper 16 and lower 12 spreading blades have through cutouts that follow side profile of vertical baffles 13 and 14 with provision of process clearance. Radial clearance between vertical baffles 13 and 14 and impact elements 6 of inner row exceeds D_max.

EFFECT: disintegrator provides, in particular, higher efficiency of the grinding process.
