A bulk-material discharge device for bunkers (1) which has to be suitable for storing, for example, brown-coal and hard-coal dust or similar bulk materials. The bulk material is to be uniformly discharged with variable output from one or more delivery nozzles (2). Bridging, caking and compaction are to be avoided. With paddle screws (3) arranged at the bottom (4) of the bunker (1) and conveying upwards at an angle, the bulk material in the bottom area is loosened and is pushed away from the delivery nozzles (2). The device is used, for example, in the intermediate storage and metering of the coal dust in furnaces fired by coal dust. <IMAGE>
