The driven rollers (3) extend from a common rotating component (5) rotatably mounted at the centre (6) of a receiving vessel (7). The support arm (4) carrying the rollers is inclined from the edge of the vessel down towards the centre of the vessel. The common rotating component is formed by a disc (5) carried by a rotating bearing (15). The disc carries a drive motor (18) to drive at least one of the rollers (3), and the rotating bearing (15) may be in the form of a hydraulic motor. A motor support sleeve (21) may project laterally from the disc (5). |
