Abstract

Device for the continuous transport of powdery or finely ground material from a space with low pressure to a space with higher pressure, by means of a conveyor screw, supported on one side, provided with a retaining flap, especially a device for the variation of the stopper of material between the end of the conveyor screw and the retaining flap, characterized in that the lever of the retaining flap is angled, the retaining flap has several regulating screws for fixing the flap in its rest position, and the conveyor screw housing on the outlet side is extended by overlapping or interposing at least one annular sector.
