In the movements of particles, the axial and radial mixings happen simultaneously, leading to greater mixing index for α = 5° and 10° as compared to the horizontal one. Compared to α = 10°, the case of α = 5° has a less axial mixing, hence a lower Lacey mixing index.

Radial segregation of granular mixtures in rotating ...

Sep 02, 1998  Simultaneous mixing and segregation of granular materials is of considerable practical importance; the interplay among both processes is, however, poorly understood from a fundamental viewpoint. The focus of this work is radial segregation—core formation—due to density in a rotating cylinder. The flow regime considered is the cascading or continuous flow regime where a thin layer of

ChE 344 - Mixing in Chemical Reactors

Axial flow impellers are very useful in mixing solid-liquid suspensions because they prevent the solid particles from settling at the bottom of the tank. The type and geometry of impeller used will vary from process to process and the determination of the best geometry for a specific process requires a great deal of experimentation.
