Ross has announced the completion of 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. This feature is especially useful for:
1. Viscous materials that have poor flow qualities
2. The addition of powders that have a tendency to float on the surface
3. When heat transfer of the batch constituents is important
The helical agitator is designed for bi-directional operation. Optional Teflon scraper assemblies can be attached to the outside of the agitator to further facilitate scraping of the sides and bottom of the vessel when operating in either the forward or reverse direction. The VersaMix is available with up to three separate agitators including the Helical agitator, a High Speed Disperser, and a High Shear Rotor-Stator Mixer. The Model VMC-75 shown includes a reverse lift that raises the mix vessel up to the fixed agitators. This change can model is manufactured in several sizes ranging from 1 through 1000 gallons. Testing is available at Ross on a no-charge basis.
