First, we perfected conventional rotor/statormixer design. Our high performance rotor/statormixers are available in sizes from benchtopthrough full-scale production, in batch and in-lineconfigurations, with a multitude of options to fine-tune ve also introduced a new, patented familyof Mixers that have opened up a new horizon inrotor/stator mixing.

4 Deagglomeration and Disintegrating Headis excellent for general purpose mixing, fast particlesize reduction of larger solids, andvigorous Slotted Headprovides the mostpopular combination of high Shear andefficient flow rates. It is well-suited foremulsions and many medium-viscositymixing Large Square Hole DisintegratingHeadis ideal for applications that requireextremelyvigorous flow and intense Fine Screen Headapplies the highestshear rates of all single-stage High ShearMixers. It is generally used for lower-viscosity emulsions and fine CLASSIC SINGLE-STAGEROTOR/STATOR MIXERAll rotor/stator Mixers are comprisedof a rotor that turns at high speedwithin a stationary stator.

5 In a single-stage unit, the rotor includesa single set of four blades. As therotating blades pass each opening inthe stator, they mechanically shearparticles and droplets, and expelmaterial at high velocity into thesurrounding mix, creating intensehydraulic Shear . As fast as material isexpelled, more is drawn into thebottom of the rotor/stator generator,which promotes continuous flow andfast Ross Rotor/Stator Mixer easilyreplaces other high speed Mixers inmany applications. With the rotorturning at 3,000 - 4,000 feet perminute (fpm), the generator appliesintense mechanical and hydraulicshear, and produces vigorous flow ina low-viscosity Homogenization, solubilization, emulsi-fication, powder wet-out, grinding andparticle size reduction, in batch andin-line configurations.

6 The single stagerotor/stator mixer is ideal for applica-tions that require fast particle/dropletsize reduction. 5 MULTI-STAGE ROTOR/STATOR MIXERSM ulti-stage rotor/stator generators include two orfour rows of rotating blades that nest inside amatching stator. The mix material enters the centerof the generator through an inlet connection andis accelerated outward by centrifugal each transit through the rotor/statorgenerator, the material is subjected to a quicksuccession of increasingly intenseshearing events until it finally exitsthe generator and iseither pipeddownstream orrecirculated foranother passthrough the mixer.

7 By applying aseriesof shearing eventswith every pass through thegenerator, the multi-stage mixer accelerates themixing process dramatically. This action alsoproduces particles and droplets that are quitesmall usually well below 1 micron in diameter and extremely uniform. LOW PROFILE X-SERIES*ROTOR/STATOR MIXERSThe rotor and stator in the X-Series generator are unique. Instead of ordinary blades in aconventional stator, the X-Series rotor and statorare comprised of many concentric rows ofintermeshing teeth.

8 The mix material begins atthe center of the generator and moves outwardthrough radial channels cut in the rotor/statorteeth. Tolerances are extremely close, and theshear applied to the material in each pass isextraordinarily intense. The Shear applied by theX-Series mixer is further intensified since thisgenerator operates at extremely high tip speeds up to 18,000 fpm. For the process engineer, the greatestadvantage of this rotor/stator design is its abilityto produce emulsions and dispersions thatotherwise would require a more expensivecolloid mill or homogenizer.

9 ApplicationsUltra-high quality dispersions and emulsions, in anin-line configuration only. X-Series units are appropriatefor applications in which sub-micron particle/dropletsize is desired to achieve the necessary productstability, visual appeal and texture especially forcosmetics, personal care and food products. *Patent No. 5,632,596 The low profile X-Seriesrotor/stator generatorintroduced the first quantumjump in rotor/stator designin 25 four-stage rotor/statorgenerator used in the RossQuad-Slot Ross Dual Rotor/Statoris a two-stage generatorApplicationsFine dispersions and high-quality other company in the world canmatch the selection and support that Rossoffers in High Shear Batch Mixers .
