The invention relates to a continuous mixing silo and a method of operating it for the mixing of fine-grained material. The silo has a base provided with a plurality of zones which are supplied with aerating air in chronological sequence. Individual zones of the base are supplied with additional air in a pulse-like manner at specific intervals of time to achieve intensive aeration and mixing of the material. The additional air is supplied from a storage unit for a shorter period than the aerating air. Air taken from the storage unit is replenished during the time interval between pulses.

Continuous mixing silo and method of operation

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.
