DISINTEGRATOR Russian patent published in 2017 - IPC B02C13/22 

FIELD: machine engineering.

SUBSTANCE: disintegrator comprises a cylindrical casing 1 with axial loading and tangential unloading devices. The body 1 has a possibility of counter-rotating wheels 4 and 5 are rigidly attached to the impact elements in rows 6 and 7, each of which is disposed between the opposing rows of impact elements disc. Disks 4 and 5 are arranged vertically. The axial loading device is in the form of two hollow horizontal screw shafts 2 fixedly connected to the disks 4 and 5. At the exit of each auger shaft 2, at the same angle to the horizontal axis of rotation of the discs 4 and 5, spreading nozzles 8 and 9 are installed. The axes of the spreading nozzles 8 and 9 intersect at points not less than 2 d_max from the impact elements 6 of the first inner row, where d_max - maximum size of crushed particles.

EFFECT: grinding process efficiency and performance of class finished crushed material due to collision of particulate material exiting the spreader nozzles in intersecting streams to the first impact elements of the inner row.
