Abstract

A reservoir for powdery media, in particular powder coating, comprises a housing having at least one inlet and at least one outlet for the powdery medium. A fluidising floor of porous, air-permeable material is located in the interior of the housing at a distance from its base. A pressure chamber which is chargeable with compressed air is located between the fluidising floor and the base of the housing. The outlet has the shape of an upwardly open funnel which is located in the lower partial zone of the housing adjacent to the fluidising floor. In this way well-mixed powdery medium the grain-size distribution of which corresponds to the maximum extent to that of the fluidised powdery medium inside the reservoir is always withdrawn.
