The term agitated fluidized bed (AFB) generally refers to a type of fluidized bed equipped with mechanical agitation. In this paper, results of an experimental study on the aerodynamic and heat transfer characteristics of an agitated fluidized bed dryer (AFBD) is presented and discussed.
Firstly, aerodynamic behavior in AFB of powders in group A, B and D of Geldart's powder groups is discussed. For each powder group, both sticky and non-sticky materials are used. It can be seen that when an agita...
