Charles Ross and Son Company, Hauppauge, NY, introduced a new Dual-Shaft VersaMix design incorporating 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. According to company executives, this feature is especially useful for viscous materials that have poor flow qualities, the addition of powders that have a tendency to float on the surface and in situations where heat transfer of the batch constituents is important. The helical agitator is designed for bi-directional operation with Teflon scraper assemblies attached to the outside to facilitate scraping of the sides and bottom of the vessel when operating in either the forward or reverse direction.
