What Is a Colloid Mill & How Does It Compare to a Homogenizer?

A colloid mill is a type of rotorstator 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 highspeed rotor pushes the fluid through small holes in a stationary stator, creating extremely high levels of mechanical shear.
