The invention relates to a device for mechanically breaking up conglomerates of materials with differing density and/or consistency, which has a breaking-up chamber with a feed opening (14) at a first end and an outlet opening (10) at a second end, wherein the breaking-up chamber has at least two portions (7, 8, 9) which follow one another in the axial direction and are surrounded by a breaking-up chamber wall (2) in the form of a cylinder or shell of a truncated cone, wherein in each of the portions (7, 8, 9) there is respectively arranged at least one rotor (4, 5, 6) with a rotor shell (17, 18, 19) and beating tools (10, 21, 22, 23, 24, 25) extending radially from the rotor shell (17, 18, 19) into the breaking-up chamber, wherein the rotor shells (17, 18, 19) of the rotors (4, 5, 6) in the portions (7, 8, 9) following one another from the first end to the second end have a radius that increases towards the second end, and a difference between the radius of the respective rotor shell (4, 5, 6) and a radius of the breaking-up chamber wall (2) decreases from the first end to the second end, and wherein the rotors (4, 5, 6) can be driven such that a direction of rotation of the rotor (6) in the portion (9) proximate to the second end is opposite to a direction of rotation of the rotor (5) in the portion (8) lying ahead thereof in the direction of the first end, and such that rotational speeds of the rotors (4, 5, 6) increase in the portions (7, 8, 9) from the first end to the second end. |
