ABSTRACT:
The invention concerns a method for the continuous production of a solid granulate by drying and simultaneous granulation in a flow bed. In this connection, the solid to be granulated, in the form of a solution or suspension, is sprayed into or onto the bed of material consisting of pregranulated solid and fluidized by an injected drying gas of suitable temperature, a corresponding quantity of granulate is discharged from the bed of material and separately therefrom the drying gas is drawn off together with the water vapor produced. In order to obtain a mode of operation independent of the flow velocity of the drying gas, the granules of the fluidized bed of material are continuously subjected to a centrifugal force classification, the mixture of drying gas and water vapor serving as carrier gas for classification.
