4 The driving force in High Shear Mixer design Ross High Shear Rotor/Stator Mixers are available with a variety of interchangeable stators to fine-tune such functions as particle size reduction, deagglomeration and emulsification. The Disintegrating Head is excellent for general purpose mixing, fast particle size reduction of larger solids, and vigorous flow. The Slotted Head provides the most popular combination of high shear and efficient flow rates. It is well-suited for emulsions and many medium-viscosity mixing applications. The Large Square Hole Disintegrating Head is ideal for...

5 MULTI-STAGE ROTOR/STATOR MIXERS Multi-stage rotor/stator generators include two or four rows of rotating blades that nest inside a matching stator. The mix material enters the center of the generator through an inlet connection 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. By applying a series of shearing events with every...

6 No other company in the world can match the selection and support that Ross offers in High Shear Batch Mixers. In sizes from 1/2 HP to 200 HP, handling batches from 50 ml to more than 6,000 gallons, Ross High Shear Mixers deliver an unbeatable combination of efficiency and flexibility. Series 100 Our Series 100 High Shear Mixers combine economy and efficiency for mixing under atmospheric conditions. Models up to 10 HP can easily be moved from one vessel to another on an optional rolling hydraulic stand – accommodating a wide range of vessel sizes. The Ross Series 500 High Shear Mixer The...

7 Typical Applications Food Chemicals Textile colors Series 500 High Shear Mixers are available in standard sizes up to 100 HP. A durable epoxy paint finish is standard, with stainless steel an option for sanitary applications. BATCH MIXING: FLEXIBILITY, HIGH FLOW AND FAST MIXING CYCLES Batch High Shear Mixers can be permanently mounted to the mix tank or suspended over the vessel with a portable lift. The mobile configuration offers you the flexibility to use a single mixer in multiple vessels. It also allows you to vary the position of the rotor/stator generator in the vessel to fine-tune...

100L High Shear Laboratory Mixer: 1/2 HP – An economical workhorse for process development in the laboratory, the 100L High Shear Mixer is equipped with a 1/2 HP motor and variable speed drive. Speeds range from 0-10,000 rpm, handling batches from 1-20 liters. Four interchangeable rotor/stator heads are standard: a Slotted Head, Disintegrating Head, Fine Screen Head and an Axial Flow Head. All wetted parts are Type 316 stainless steel, and they are easily disassembled for cleaning. 100LC High Shear Laboratory Mixer: 1 HP – The most powerful and versatile rotor/stator mixer ever built for...

9 Model 405SB-25 In-line SLIM – Turn-key skid-mounted systems are also available with custom control packages and fabricated vessels. This sanitary, 25 HP In-line SLIM System was built for a personal care products manufacturer. Solids are added using the hopper mounted in the center of the system. New Technology for High Speed Powder Induction Powders like fumed silica, calcium carbonate, titanium dioxide, gums, thickeners and many pigments are notorious for driving up processing costs. Even with a strong vortex in an open vessel, they resist wetting out and often float on the surface for...

10 Ross High Shear In-line Mixers Model 703X-10 High Shear In-line Mixer: 10 HP – The smallest of the X-Series mixers. Its 3" rotor generates tip speeds in excess of 11,000 fpm – and thousands of intense shearing events with each revolution. A Ross High Shear In-line Mixer is a versatile choice for process lines that require frequent changeover from one product to another. A simple valve can divert finished product downstream or switch instantly from one source vessel to another. Between-batch cleaning is easy. Interchangeable rotor/stator generators provide virtually unlimited flexibility...

11 Model 400DL High Shear In-line Mixer: 1 HP – A recirculating system enables you to fine-tune your final particle/droplet size and distribution. This is particularly useful in benchtop development, since scale-up with Ross High Shear Mixers is highly predictable. Model 405S High Shear Mixer: 5HP – All Ross High Shear In-line Mixers can be provided with a jacketed vessel to closely control batch temperature during recirculation. Data from temperature probes located in the vessel can be fed to a Ross-designed control system for automated control of a cooling/heating system. Series 700...
