About Rotor-Stator Mixers

Rotor-stator mixers are single-shaft mixers with an impeller rotating in close proximity to a stationary housing. They are used to rapidly break apart solid particles in a liquid, or to emulsify a liquid into liquids. The impeller or rotor mechanically imparts high-shear forces to the ingredients. With rotor-stator mixers, clumps of particles are also broken apart by the hydraulic shearing forces generated as they are ejected through openings in the stator into the rest of the batch. In addition, rotor-stator mixers are effective at chopping coarse particles such as rubber or flake resin. The stator directs the flow and confines the particles while the rotor imparts shear.
