A silo or the like for storing pulverulent, granular or lumpy material has a wall which encloses the silo storage space, a roof whose pitch substantially corresponds to the angle of repose of the material, an inlet opening in the silo roof, an outlet opening in the silo floor, and a screw conveyor suspended from a beam rotatable about the axis of the silo. The beam is inclined downwardly from the inlet opening of the silo and extends substantially parallel to the roof pitch, and the conveyor is suspended from the beam by means of wires which are adjustable independently of each other with respect to their length. The conveyor can thus be anchored close and parallel to the supporting beam when material is fed into the silo, and be disposed at a suitable angle, preferably inclined downwardly toward the center of the silo, when material is discharged from the silo.
