A colloid mill is a type of rotor-stator mixer often used in the manufacturing of emulsions and dispersions. It can also be used to reduce the particle size of solids in suspension. Inside the colloid mill, a high-speed rotor pushes the fluid through small holes in a stationary stator, creating extremely high levels of mechanical shear.
