The colloid mill grinding mechanism for solids relies on the material being sheared and compressed as it passes between the closely spaced rotor and stator surfaces, often serrated or grooved to enhance the effect. Combined with turbulence and impact, this shearing action fractures solid particles suspended in the liquid carrier, gradually reducing them to a fine colloidal size suitable for suspensions.
