1 Innovation inMulti-Shaft Mixers 2 Ross Multi-Shaft MixersTHE WORLDWIDE STANDARD FOR DESIGN AND INNOVATIONRoss is the leading manufacturer of Multi-Shaft Mixers and has beensince we introduced the original Multi-Shaft Mixer over 80 years , Ross operates five plants in the USA, along with Ross ownedplants in China and India. Ross can deliver a combination of economy, productivity and fast delivery that no other company can match. The Ross family of multi shaft Mixers includes sizes from 1/2 - gallon to 4000 gallons capacity and a multitude of options to meet the needs of mostindustrial WORLD S LARGEST INVENTORY OF Mixers INSTOCK FOR FAST DELIVERYOur multi-million dollar inventory of Mixers and blenders is yourultimate assurance that you can have the equipment you need,when you need it.

You will see that allmulti-shaft Mixers are not the design innovations like the useof special dry running seals forsanitary applications, or a lubricatedbushing system for the rotor statormixer give Ross customers a terrificadvantage.

3 All Ross Multi-Shaft Mixersare built with generous shaft supportsto eliminate the concern overmaintenance issues. Our engineeringand fabrication facilities are uniquelyequipped to handle the job, at areasonable cost, for standard orcomplex designs. 4 The Ross DifferenceThe Ross Multi-Shaft Mixer is a proven design to meet the changing requirements of today smajor process Multi-Shaft Mixers are tailored to suit the individual process demands of customersmanufacturing products that range from low tohigh viscosity. This is possible by selecting thebest combination of the three agitation systemsoffered with this are available in fixed tank andchange-can designs.

4 Change-can units are builtthrough 1000 gallons capacity whereas fixedtank models are available to 4000 gallonscapacity. An extensive range of designcombinations, horsepower selections andoptional features are available with each Wing Anchor AgitatorProvides movement of materials to high speed mixersHigh Speed DisperserDisperses solids into viscous liquidsHigh Shear Rotor/Stator MixerUsed for products that require very fine dispersions andemulsificationMODEL VMC-100 VACUUM MIXER DUAL OR TRIPLE SHAFT DESIGNS TO FIT YOUR EXACTPROCESSING NEEDSWe offer Dual and Triple Shaft designs to meet yourspecific process requirements.

5 Our economicalDualShaft design includes a conventional high speeddisperser and a two wing anchor agitator. Thisconfiguration is ideal for straight forwarddispersion and mixing Triple Shaft design extends the operatingrange of this product line by adding either a highshear rotor/stator mixer, or a second high speeddisperser. The addition of a high shearrotor/stator mixer adds the capability ofemulsifying and homogenizing products thatrequire higher Shear to reduce the size of theparticles being mixed. The Dual Shaft and the Triple Shaft designsare available in standard or sanitaryconfigurations.

6 They can be customized to meetany special process considerations such asvacuum or pressure operation. 5 High Shear Rotor/Stator MixerThe high speed close tolerancerotor and stator provide highshear to all materials beingpassed through the rotor/statorgap. This intense shearing actionis used to reduce particle size forhomogenization, dissolution andemulsification. Used alone thismixer is best applied withmaterials having a maximumviscosity of 10,000 centipoise. In conjunction with the anchor itsuseful range can be extended toover 100,000 Speed DisperserThe conventional dispersionblade is used to disperse solidsinto viscous liquids that arebeyond the viscosity range ofthe high Shear rotor/stator mixer and anchor combination.

7 This mixer is best applied byitself in a viscosity range up to 50,000 cps and inconjunction with the anchor to over a million Wing Anchor AgitatorThe three wing anchor agitator isdesigned to provide maximummovement of product under lowshear conditions. It movesmaterials in radial and axialdirections to feed the product tothe high speed mixer heads. It is also used to improve heat transfer by constantly movingstagnant materials from theinterior tank walls. Teflon scrapersattached to the anchor can assistin heat transfer. The shape of theanchor makes it easy to cleanbetween batches.

8 When all three agitators are used, the mix cycle is usually shorter whencompared to dual shaft three separately driven agitatorswork in concert with each other toproduce a thorough mixture of allproduct components. Model CDA-1000 Triple Shaft MixerTriple Shaft Mixers above 300 gallons working capacity aresupplied in single and dual post hydraulic lift design. Most Multi-Shaft Mixers are supplied with stainless steel wetted parts. The Anchor and two High Speed Dispersers are independentlyvariable speed. The ASME code constructed and stamped jacketis insulated and sheathed in stainless steel.

9 Complete controlpanels are normally supplied to enable fast startup upon further details see specification VMC VersaMixThis triple shaft model is ideal for research anddevelopment activities. This mixer is available in 1, 2 and4 gallon sizes. It allows users to develop new productswith the confidence they can scale up to production mixer is designed with the user in mind with allstainless steel wetted surfaces, also optional features areavailable such as vacuum construction, a jacket to heat orcool a choice of agitator designs, our two or three wingconfiguration, or the newest helical mixer controls are built into the mixer housing topermit single point hook up upon receipt of the mixerfrom the factory.

10 Model CDA-50, 100 and 200 Gallon Dual ShaftMixers are normally available in stock for immediate include vacuum hoods for operation to 29-1 2 Hg, anda single post air/oil hydraulic lift system. Our Dual ShaftMixers are supplied in a wide range of sizes from 1 through1000 gallons capacity. Mix vessels are available with ajacket to provide heating or cooling and can be mounted onnon-sparking caster wheels for ease of movement within theplant. The drives include explosion proof motors and eachagitator is independently driven for precise mixing control."For further details see specification Production SystemComplete computerized systems can automate yourmixing process and ensure consistency and mixing parameters from individual agitator control tovacuum and thermal control, and raw material addition,at key process stages can be pre-set for a variety of mixrecipes.
