Summary
This chapter addresses the use of rotor-stator mixing devices in the chemical process industries. While the chapter is mostly practical in its outlook, some attempt is made to relate design and scale-up to process fundamentals. This is difficult since basic knowledge of high shear mixer performance has only recently begun to emerge. An introduction to the subject is followed by a discussion of the geometry and mechanical design of various device types. Hydrodynamic issues are addressed with respect to available data for power draw, pumping capacity and internal flow field details, and their effect on emulsification and dispersion mechanisms. Process scale-up and design for liquid–liquid dispersion, power/solid–liquid dispersion and chemical reaction are also considered. Concluding sections include mechanical design and equipment vendors.
