Working and Principle of colloidal Mill | Pharma Pathway
Working of the Colloidal Mill. The material is placed into the mill though the inlet hopper. It is then passed through the narrow gap between the rotor and stator and thus reduced the fine particle size. A colloid mill is a hydraulic shear producing device. The colloid mill works to reduce the size of the suspended droplets.
