The aim of this paper is to provide practical information on the efficient use of specialty mixing equipment for the preparation of low, medium and high viscosity nanodispersions.
High Viscosity Mixer Designs and Applications
Efficient mixing of viscous applications takes into consideration, among many other factors, viscosity and level of shear. It is common for batch materials to exhibit fluctuating rheology during different stages of mixing and demand varying shear intensity depending on ingredient additions or temperature limits. The appropriate mixing equipment must therefore have the ability to control flow pattern and fine tune shear input at any point of the mix cycle.

This white paper presents some strategies for improving commonly encountered batch mixing problems. Because mixing processes vary from one application to another – with different objectives, design configurations, rheologies, operating limitations, etc. – there are no fix-all solutions that will apply to every situation.
