Charles Ross & Son Co. reports that its VersaMix triples-shaft mixers with solids/liquid injection manifold (SLIM) technology are an ideal choice for challenging mixing applications requiring efficient powder dispersion and critical homogenization of medium- to high-viscosity slurries, pastes, gels, creams, and suspensions. The VersaMix models VMC-40 pictured here were designed for full vacuum operation and include: a three-wing anchor agitator with Teflon™ blades scraping the sidewalls and bottom surfaces of the vessel; a high-shear mixer with SLIM-style rotor/stator, which draws solids sub-surface for virtually instantaneous wet-out; and a high-speed disperser that continues to apply shear as the batch increases in viscosity.

Fine dispersion, deagglomeration, emulsification, temperature control, and degassing are all accomplished in the VersaMix in a highly repeatable process, according to the company. The vacuum cover features an explosion-proof tank light, RTD thermoprobe, CIP spray nozzles, and a dedicated port for nitrogen purging.
