  • Patent number: 6244850
    Abstract: The invention relates to a pelletizing press (1) with a drum (2), comprising a drum axis (6) and at least one press roller (3) which is accommodated in the drum (2) in such a way that it can rotate about a press roller axis (8). The press roller is driven about the press roller axis by roller drive means (7, 27, 28, 29). The press roller (3) and/or the drum (2) are also rotated about the axis of the drum by rotation means. Furthermore, roller adjustment means (11, 12, 13, 16) are provided for varying the distance between the press roller and the drum wall. By designing the roller drive means, the rotation means and the adjustment means in the form of three concentrically situated shafts, an adaptation of the position of the press roller (3) can be obtained during continuous operation of the pelletizing press (1), in other words, during rotation of the press roller (3) about its axis and during rotation of the press roller (3) and/or the drum (2) about the drum axis (6).
