20120325949 | DEVICE FOR MECHANICAL SEPARATION OF MATERIAL CONGLOMERATES FROM MATERIALS OF DIFFERENT DENSITY AND/OR CONSISTENCY - A device for mechanical separation of material conglomerates includes a separating chamber with a feed side and a discharge side, where the separating chamber is surrounded by a cylindrical separating chamber wall and has at least two consecutive sections, in each of which at least one rotor with impact tools, wherein the rotors have 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. | 12-27-2012 |
