As we know, the colloid mill is used to smash and reduce the size of particles from the solid that is suspended in a fluid. When a liquid is immiscible with another liquid, we need the colloidal mill be used to emulsifying it and in reduction of the particles.
The colloidal mill is used in different industry for those solution emulsifying or particles reduction, especially in pharmaceutical manufacturing.
The working step of colloidal mill is like the product is passed through the hopper on the top of the mill,then passed through the narrow gap between rotor and stator.The teeth type rotor and stator shear the material into the particles with speed 2900rpm which can be adjusted too. It mainly works on the material that will be suspended on the liquid or emulsion. This mechanism is used for various purposes in the pharmaceutical fied like dispersing of solid particles in a emulsion,milling and homogenization and improving the stability of emulsions.
Pharmaceutical companies work with small compound particles. They seek to separate chemical compounds to get to the smallest state of the compounds. That's why the colloidal mill is important in the pharmaceutical filed.
