The device relates to an autogenous rotor that rotates about an axis of rotation, which rotor is provided with at least one guide member for accelerating material, which guide member is associated with a chamber member where an autogenous bed of material builds up, with the aid of which guide member material is guided into a spiral path in the direction of the chamber member where the accelerated material impinges on the autogenous bed at a predetermined impingement location, after which the material moves from the impingement location along the autogenous bed in the direction of the tip, under the influence of centrifugal force, where the material is propelled outwards from the rotor. |
