Dispersing systems are used to produce emulsions of two immiscible liquids or dispersions of solid particles in a liquid medium. The mixers generally operate on the rotor/stator principle and apply a high shear force on the suspended particles to break them down. The choice of a dispersion mixer depends on the physical state of the material being dispersed, the continuous or batch nature of the process, desired particle size, and the viscosity of the mixture. Dispersion mixers are widely used in the food industry for the dispersion of solid ingredients in oil or water and in the coatings industry for the dispersion of pigments.
