A colloid mill is used in the size reduction of solids and droplet present in suspension or emulsion (Fig. ). A colloid mill consists of a rotating cone (rotor), a static cone (stator), and a feeding unit. The size reduction mainly takes place due to the shearing action in the narrow gap between the rotor and stator.
