Inside the Colloid Mill

Roto-Mill logo

Sonic Corp’s RotoMill colloid mills and grinding mills are designed to provide superior shearing and grinding. Using a patented and proven multi-angular system, our rotors and stators  operate with 3 shear points that subject material to a higher degree of grinding than conventional mills. Undispersed material is forced into a cavity formed by a spinning rotor and fixed stator. Centrifugal force propels the material to the outside of the rotor, causing intense hydraulic shear that breaks agglomerates and homogenizes the solids and liquids.

Sonic has modernized Colloid Mill technology!

Milling technology dates back to the early 1900’s without many groundbreaking improvements over the years. Here at Sonic Corporation, we have modernized an age old technology by combining the mill seal chamber with a movable housing that allows the rotor gap to be adjusted without hampering the seal face connections.
