Abstract

A container bottom for the pneumatic discharge of fine material from a container comprises a plurality of conveying channels extending radially to a central material discharge zone of the bottom, the bottom of the central material discharge zone being disposed lower than the bottom of the conveying channels to obtain a uniform passage of the material from the conveying channels to the central material discharge zone.
