Abstract
The invention relates to a method and a device for the metered removal of a fine to coarse-grained solid matter or a solid matter mixture from a storage container, comprising a device for forming a fluidized bed in the discharge region or in a metering chamber of the metering container, wherein fluidization that is as optimal as possible is to be created in the lower region of such a receiving or metering container while avoiding any additional systems, mechanical elements, or extensive installations. This is achieved according to the method in that a gas is additionally introduced in the region of the metering chamber bottom for forming a fluidized bed that loosens the solid matter, and a gas is introduced via swirl nozzles for bringing about the rotation of the fluidized bed.
