Abstract
The bulk material silo has a venting bottom containing a fiber layer (4). To compensate the difference in flow-off resistance, which differs with the distance of material from the discharge (6), it is provided that the fiber layer differs in flow resistance (10) along the path of the material toward the outlet (6), specifically having a lower flow resistance in regions further away from the outlet.
