Mixing of Binary Mixture in a Spout-Fluid Bed

In many industrial applications of dense gas-solid fluidized beds, mixing and segregation phenomena play a very important role [1]. The hydrodynamic behavior of binary fluidized beds is strongly influenced by the difference inproperties of the respective particles, especially in density and size [2]. However, in industrial solids mixing, it is often required to mix particles differing widely in physical properties viz., size, density and/or shape.Rice et al. [3], Hoffmann et al. [4], Wu et al. [5], Sahoo et al. [6] and Bokkers et al. [7] investigated the mixing and segregation of the narrowsize distribution of binary particlesin fluidized beds.
