Abstract:
1. A method for the treatment of fine-grained material in a spouted bed, comprising supplying fluidizing means from a bottom of the spouted bed into a process chamber to create and maintain a spouted bed processing flow, creating a gas flow of the fluidizing means in the process chamber ( 5 ) via an exterior annular gap ( 7 ) located in a y-z-plane, that is almost circular and having a diameter expanding in a direction of an x-axis in the processing chamber ( 5 ) towards an outside, creating an almost circular gas flow of the fluidizing means via an interior annular gap ( 8 ) located in the y-z-plane, with a diameter expanding inwardly in the direction of the x-axis in the process chamber ( 5 ), and adjusting an influx direction of the gas flow supplied via the exterior ( 7 ) and the interior annular gap ( 8 ) via adjustment of a central displacer ( 2 ).
