Abstract
Worm conveyor for bulk material, the outlet of which is separated from an outlet chamber, in which a higher gas pressure obtains than at the inlet of the worm conveyor, by a non-return flap, which is pressed by a flexible force into the closed setting. The operating behaviour of the conveyor is improved, in particular drive power and wear are reduced, in that a damper is provided for damping the movement of the non-return flap, in particular for damping the opening movement.
