Applications of Rotor-Stator Mixers

Rotor-stator mixers are used in the chemical, biochemical, agricultural, cosmetics, and food-processing industries. They are employed in many process operations that involve  

Their major use includes the production of latexes, adhesives, personal care and cleaning products, dispersion and microdispersions of chemicals, and agricultural pesticide formulations. These dispersions, in general, have a viscosity less than 150 Pa s (150 000 cP). When the viscosity of the flnids or dispersion is much greater than this, extruders are employed instead of rotor-stator mixers.

The literature is small on rotor-stator devices, as discussed in Chapter 8. [They are also discussed in Chapter 12, since this is the process result (liquid-liquid and solid-liquid) that these devices are most used for.] It should be mentioned that because of their very high speed they can produce turbulent motion in some rather high viscosity fluids. Also see Cohen (1998), Dietsche (1998), and Myers et al. (1999) for general information about the industrial application of rotor-stator mixers versus other mixing options.
