Abstract

The invention relates to a method and arrangement for releasing material 7, which forms hollows, between a discharge screw conveyor 3 arranged at the bottom 2 of a silo 1, the discharge screw conveyor having a rotatable body part 5 pivoted about an axis 4 essentially perpendicular to the bottom of the silo, and an emptying worm 6 projecting from the body part essentially in the direction of the bottom, which emptying worm is designed to empty the material 7 in the silo via the body part of the emptying worm, the cover part 8 of the body part 5 and wall 9 of the silo 1. In the method according to the invention an instantaneous relative movement is produced between the cover part 8 of the body part 5 of the emptying worm 3 and the material 7, which has formed hollows in the silo 1, or the said relative movement already underway is instantaneously rendered more effective. <IMAGE>
