All rotor/stator mixers are comprised of a rotor that turns at high speed within a stationary stator.
In a “single-stage” unit, the rotor includes a single set of four blades. As the rotating blades pass each opening in the stator, they mechanically and hydraulically shear particles and droplets, and expel material at high velocity into the surrounding mix. As fast as material is expelled, more is drawn into the rotor/stator generator, which promotes continuous flow and fast mixing.
Multi-stage rotor/stator generators include two to four rows of rotating blades that nest inside a matching stator. The mix material enters the center of the generator through an inlet pipe and is accelerated outward by centrifugal force. During each transit through the rotor/stator generator, the material is subjected to a quick succession of increasingly intense shearing events until it finally exits the generator and is either piped downstream or recirculated for another pass through the mixer.
The Ross Rotor/Stator Mixer easily replaces high speed dispersers in many applications. With the rotor turning at speeds up to 18,000 feet per minute (fpm) the generator applies intense mechanical and hydraulic shear, and produces vigorous flow in a low-viscosity batch.
