Abstract. Size reduction is one of the most common unit operations for both active pharmaceutical ingredient (API) and drug product manufacturing.The resulting particle size distribution (PSD), in most cases, is believed to have great impact on bioavailability and/or downstream processes. However, the fundamental understanding of the process is still limited.

Colloidal mill works on the principle of rotor-stator. The size reduction is affected due to shearing, when the material is passed between the narrow gap of milling surfaces of rotor and stator. A rotor turns at high speeds of 3000 – 20000rpm. The high levels of hydraulic shear applied to the process liquid disrupt structures in the fluid.
