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 casing 1 has a possibility of counter-rotating discs 4 and 5 with impact elements 6 and 7 rigidly attached thereon in rows, each of which is disposed between the rows of impact elements of the opposite disc. Discs 4 and 5 are arranged vertically. The axial loading device is in the form of two hollow horizontal auger shafts 2, rigidly fixed to discs 4 and 5. Two outer hollow cylinders 9 of larger diameter and inner ones 8 of smaller diameter are coaxially and rigidly attached to the working surface of each disc 4, 5. Inside the hollow cylinders 8 and 9, the radial accelerating blades 10 and 11 are rigidly fixed to the working surface of discs 4 and 5. The walls of the inner hollow cylinders 8 are made in the form of sieving surfaces with through holes of diameter (0.05…0.1) d_Max. The distance between the ends of the hollow cylinders 8 and 9 is greater than 2 d_Max, where d_Max is maximum size of grinded particles.

EFFECT: disintegrator is characterized by a more efficient grinding process and efficiency by the finished class of the grinded material.
