Inline Rotor Stator Mixers

The Inline Model High Shear Rotor-Stator mixer design consists of a single, dual or four stage rotor that turns at high speed within a stationary stator. As the rotating blades pass the stator, they mechanically shear the contents. The Inline model is a good choice for process lines that require frequent changeover from one product to another.
