Abstract: In a self-supporting stirrer for mixing a bed of free-flowing solids, the lower end of the stirring device, facing the bottom of the stirred vessel, passes into a hub. The hub is located on a vertical drive shaft which extends through the bottom of the stirred vessel and consists of shaft sections detachably joined to one another. The drive shaft itself is carried in a cage attached to the bottom of the stirred vessel and can be adjusted vertically by means of a lifting device. This opens or closes an annular gap between a centering cone, provided at the bottom of the stirred vessel, and a conically recessed ring, inserted in the hub. In this way, the need to empty the vessel, for example when carrying out maintenance or repair work, is avoided.
