Charles Ross & Son Co. has announced the completion of a new Dual-Shaft VersaMix design that incorporates a special helical agitator and high-speed dispersion blade. The new combination of agitators provides improved axial and radial turnover of the materials being mixed, as well as high shear of the product. The helical agitator is designed for bi-directional operation. Teflon scraper assemblies are attached to the outside of the agitator to facilitate scraping of the sides and bottom of the vessel when operating in either the forward or reverse direction. The VersaMix also includes special high-pressure cleaning nozzles, mechanical seals, a side-entering mix can configuration and explosion-proof controls mounted on the side of the mixer. This change can model is manufactured in several sizes ranging from 1 to 1,000 gallons. Testing is available at Ross on a no-charge basis.
