Hi, Welcome to factory !
Director of Mixing Technology ... Shaft can be raised for start-up. Then lowered as bed of particles is suspended. WHAT IS MIXING Etchells Mixing is the application of mechanical motion in order to create ... Impeller characteristics are rigorously quantified
Impeller, shaft and coupling are of type 304 Stainless Steel. The Fawcett Mixed Flow self-centering satin finish Impeller furnished as standard is 6 in dia. with high lift pitch. It is designed to quickly force settled material into suspension with a minimum of vortex and swirl.
Countercurrent flow impeller that substitutes expansive helical ribbon impellers by state-of-the-art design. ALPHA creates a forced driven flow all over the tank with constant mixing times independent of the flow number. Runs up to viscosities 1 million cP. Due to its optimized construction, ALPHA be assembled into tanks through each manhole.

You can choose mixing time as per your requirements. My program will recalculate the diameter of the impeller and shaft rpm.
Typically the impeller is a single propeller or turbine blade connected to a shaft that is driven by an electric motor at a fixed speed. There are two classes of impeller agitators axial-flow and radial-flow, and the mixing characteristics are shown in Figure 2. Axial-flow impellers generate currents parallel with the axis of the impeller shaft.
Apr 07, 2006 impeller, that is, K S N 1 where K S is a nondimensional constant, dependent on impeller geometry, and N is the shaft speed revs. This concept has since been widely accepted and used in non-Newtonian uid mixing studies.2-8 In the original work by Metzner and Otto,1 the ow of a Rushton turbine operating in two non-Newtonian shear-thin-

Jun 06, 2020 The F3 is a versatile impeller, suitable for high mixing efficiency in high and low viscosities, increased scouring velocity and low shear rate, making it the ideal mixing impeller. The three-ear hub is keyed to the agitator shaft with the blades bolting onto it, together with the shaft

the mixing impeller. These loads are dynamic and are transmitted from the impeller blades to the mixer shaft and gear reducer. A general result for the form of the fluid force equation can be developed. The importance of the mechanical interaction of the mixing process with the mixing vessel and impeller
and small impeller diameter will result in lower torque and therefore a lower mixing level than a larger impeller turning at a lower speed. Impeller Styles Mixing impellers fall into one of two categories Radial Flow or Axial Flow. Radial flow impellers have multiple flat blades mounted parallel to the axis of the mixing shaft.
This axial flow impeller is effective for low shear mixing. The 25 mm 1 in diameter blade fixes to an 8 mm in diameter shaft with included set screws. Blade and shaft are both 316L stainless steel, with the propeller blade electropolished finish and the shaft with passivated finish.
Feb 09, 2016 RE Multiple impellers in one shaft mixing design question geesamand Mechanical 13 Jul 16 1156 I realize this is an old thread, but maybe this can still help.
Jul 11, 2013 The mixing of viscous Newtonian fluids was investigated in experiments by means of decolorization visualization. Various inclined shaft and offset impeller configurations were tested to develop complete mixing with less energy consumption. It was found that isolated mixing regions could be more easily destroyed with larger angles of inclination, for example, 30 . A specific energy

Dec 01, 2016 Strategy of the shaft eccentricity is introduced to enhance the mixing characteristics in a flat bottomed cylindrical vessel without baffles. The mixing is ensured by a six-curved blade impeller. Three solutions which are models of food emulsions are used as working fluids. These solutions have a shear thinning behavior modeled by the power-law.
