AB - This paper presents the results of the kinetics research into the drying of  fine grained material in a two-component fluidized bed. A review of  theoretical and experimental investigations of aerodynamics of the fluidized  bed is given, with a special insight into two-component fluidized beds, as  well as the basics of heat and material transfer through a fluidized bed.  Apart from the theoretical basis of convective drying of wet materials in a  stagnant fluidized bed, the paper also emphasizes different approaches to  fine grained material drying kinetics. Based on the experimental  investigations, where zealots used as a representative of fine grained  material and polyethylene as a representative of inert material (another  component), an analysis of the influence of working parameters on drying in a  two-component fluidized bed is performed. It is established that, apart from  the influence of the considered parameters, such as fluidization velocity,  diameter of fine grained material particles and drying agent temperature, on  the drying curve, the participation of inert material can considerably  increase the intensity of heat and material transfer in the fluidized bed. A  comparison of the experimental drying curves of fine grained material in the  two-component fluidized bed with the results from the studies by other  authors shows satisfactory agreement.
