Charles Ross & Son Co. offers its ROSS VersaMix triple shaft mixer, which handles challenging mixing applications requiring efficient powder dispersion and critical homogenization of medium to high viscosity slurries, pastes, gels, creams and suspensions, the company says. The VMC-40 (pictured above) is designed for full vacuum operation and includes a three-wing anchor agitator with Teflon blades scraping the sidewalls and bottom surfaces of the vessel. The VMC-40 also features a high shear mixer with solids/liquid injection manifold (SLIM) technology, which draws solids sub-surface for virtually instantaneous wet-out. A high speed disperser allows the mixer to apply shear as the batch increases in viscosity. The highly repeatable mixing process features fine dispersion, deagglomeration, emulsification, temperature control and degassing, which are all accomplished in the VersaMix in a highly repeatable process, it says. The vacuum cover features an explosion-proof tank light, RTD thermoprobe, clean-in-place spray nozzles and a dedicated port for nitrogen purging.
