Abstract (en)

The method involves rendering a poorly pourable bulk material e.g. sawdust, by a worm conveyor (1), where the worm conveyor is fixed on a shaft (3) and the rotation of the shaft causes the bulk material to be transported upward to a bulk material surface. The poorly pourable bulk material is discharged from a receptacle (4) by a spiral conveyor. The worm conveyor and the spiral conveyor are mechanically coupled to one another. The worm conveyor and the spiral conveyor are fixed on the shaft. An independent claim is also included for a poorly pourable bulk materials discharging device comprising an opening.
