DEVICE FOR MECHANICAL SEPARATION OF CONGLOMERATION, CONSISTING OF MATERIALS WITH DIFFERENT DENSITIES AND/OR CONSISTENCIES Russian patent published in 2016 - IPC B02C13/14 B02C13/20 

FIELD: disintegrators and devices for crushing.

SUBSTANCE: device comprises a breaking-up chamber with feed opening 14 at a first end and outlet opening 10 at a second end, wherein breaking-up chamber has at least two portions 7, 8, 9 which follow one another in axial direction and are surrounded by breaking-up chamber wall 2 in form of a cylinder or shell of a truncated cone. In each of portions 7, 8, 9 there is at least one rotor 4, 5, 6 with rotor shell 17, 18, 19 and beating tools 20, 21, 22, 23, 24, 25. Beating tools extend radially from rotor shell 17, 18, 19 into breaking-up chamber. Radius of shells 17, 18, 19 of rotors 4, 5, 6 in sequential portions 7, 8, 9 increases from first end to second end. Difference between radius of respective rotor shell 4, 5, 6 and a radius of breaking-up chamber wall 2 decreases from first end to second end. Direction of rotation of rotor 6 in portion 9 facing to second end can be opposite to direction of rotation of rotor 5 in portion 8 arranged ahead of it in direction of first end, and rotation speed of rotors 4, 5, 6 in portions 7, 8, 9 increases from first end to second end.

EFFECT: providing crushing of conglomerates of materials with different densities and/or consistencies.
