ROSS: Dual-Shaft Mixers
Dual-shaft mixers from this company can reportedly deliver a balance of bulk flow agitation and high-speed dispersion required in the processing of viscous pastes, gels, suspensions, slurries, and emulsions. These machines feature two independently driven agitators that run at different speeds, imparting varying levels of shear and ensuring adequate turnover over a wide viscosity range. Production models are offered in many standard sizes up to 4,000 gal capacity.
Pictured is a dual-shaft mixer model CDA-500 with a maximum working capacity of 500 gal. An air/oil hydraulic lift raises/lowers the agitators from/into the mix can. NEMA 12 safety limit switches reportedly prevent operation of the drives when the mix vessel or agitators are not in the proper position. All product-contact parts are stainless steel 304 with mill finish and welds ground smooth. The heavy-duty two-wing anchor agitator and dual-blade high-speed disperser are driven by 10HP and 100HP inverter-duty motors, respectively. Hinged Teflon scrapers are attached to the anchor for wiping of the vessel sidewall and dished bottom. A tungsten carbide coating on the saw-tooth disperser blades can allow the mixer to be used with abrasive materials.
