MIXER WITH A CENTRAL CIRCULATING TUBE

Abstract

The hydrodynamic properties of a mixer with a central circulating tube were studied. Mixed contents were created from different liquids: water, water - saccharose and water - glycerine, from two-phase mixtures: water - air, water - glass spheres and from three-phase mixtures: water - air - glass spheres. A new functional relationship was proposed between the energy consumption and Re number for the mixing - homogenization process and it was successfully used in the evaluation of measurement results. It was possible to describe the complete suspension of glass particles in water by Rieger´s Π criterion, which was also suitable for describing the mixing process of the three-phase mixture.
