Characterization of mixing in shaker table containers

Abstract

Mixing in shaker table beakers is studied using dye dispersion to measure mixing times. Experimental conditions range from the laminar regime into the turbulent mixing. Different flow patterns occurring in the beakers are reported for the mixing. The transition Reynolds number is determined. Rotational speed of the table, volume of material to be mixed, and viscosity of the material are studied as to their effects on mixing time. A graphical mixing time correlation is provided which is useful for the translation of mixing from laboratory scale to pilot scale.
