Abstract
In order to avoid caking of bulk material when feeding from a feeder into an inlet opening of lesser cross-section, there is provided a trough with a central discharge opening located below the discharge of the feeder. Two double paddle conveyors extend in the trough towards the central discharge opening. A vertical gravity tube joins on the trough. The tube is surrounded by one or several annular channels guiding a gaseous medium. This medium forms a gaseous screen between the bulk material flow and the gravity tube.
