<p>Screw conveyer (1) for bulk material, the outlet (5) of which is separated from an outlet space (7), in which a higher gas pressure than at the inlet (4) of the screw conveyer (1) prevails, by a non-return flap (8) which is urged into the closing position by a resilient force (14). The operating behaviour of the conveyor is improved, in particular the drive power and wear are reduced, by the provision of a damper (13) for damping the movement of the non-return flap (8), particularly for damping the opening movement. <IMAGE></p> |
