Summary A tumbling, oloid hollow body (4) is placed on freely moving rollers (51) that cause its tumbling motion to receive materials. The tumbling motion is forced by the fact that the trace points of the axis of a hollow shaft (6) piercing the hollow body (4) in its longitudinal axis are forced onto oval paths by two planes parallel to each other that are upright and are defined by a frame (11). Each of these frames (11) carries a vertically moveable and driven slide (60) forming itself a guiding element for a horizontally moveable and driven slide (61). Each of these horizontally moveable slides (61) holds a ball (62), pierced by the shaft (6), forming the bearing and guiding element for it. The slides (60, 61) are driven by a control (63) that stores the position-time-speed profile comparable to the tumbling motion. The tumbling hollow body (4) has a closeable opening (5) for the addition and removal of mixing material. If the shaft (6) is hollow, mixing materials can be added and removed during the tumbling operation by means of rotary passages on both ends of the hollow shaft (6). (Fig. 6)
