Abstract:
1. A device for mechanical separation of material conglomerates from materials with different density and/or consistency, comprising: a separating chamber with a feed side; and, a discharge side, where said separating chamber is surrounded by a cylindrical separating chamber wall and has at least two consecutive sections in the axial direction, in each of which at least one rotor has impact tools which extend radially into the separating chamber, wherein the rotors have, in the consecutive sections from the feed side to the discharge side, a rotor casing, the radius of which increases towards the discharge side, wherein the difference between the radius of the rotor casing and the radius of the separating chamber wall decreases from the feed side towards the discharge side, the directions of rotation of the rotor in the section facing the discharge side and the rotor of the section which lies ahead in the direction of the material flow are counter-rotating, and the rotational velocity of the rotors in the sections from the feed side towards the discharge side of the separating chamber, increases.
