Colloid mills are the preferred technology for highly viscous emulsions (> 5000 cp) commonly encountered in industry. A typical colloid mill consists of a conical rotor that rotates inside a static stator. As the emulsion is passed through the narrow gap between the rotor and stator, drop breakage occurs due to intense shearing.
