Abstract

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.
