Dual shaft mixer design.The Dual-Shaft VersaMix design incorporates a helical helical /hel·i·cal/ (hel´i-k'l) spiral (1). hel·i·cal adj. 1. Of or having the shape of a helix; spiral. 2. Having a shape approximating that of a helix. agitator ag·i·ta·tor n. 1. One who agitates, especially one who engages in political agitation. 2. An apparatus that shakes or stirs, as in a washing machine. Noun 1. and high-speed dispersion blade. This combination of agitators is said to provide improved axial and radial turnover of the materials being mixed, as applying high shear to the product. This feature is said to be especially useful for viscous viscous /vis·cous/ (vis´kus) sticky or gummy; having a high degree of viscosity. vis·cous adj. 1. Having relatively high resistance to flow. 2. Viscid. materials that have poor flow qualities, the addition of powders that have a tendency to float on the surface and when heat transfer of the batch constituents is important. The helical agitator is designed for bi-directional operation. Teflon scraper See scraping. assemblies are attached to the outside of the anchor agitator to facilitate scraping of the sides and bottom of the vessel when operating in either the forward or reverse direction. The VersaMix can also incorporate a high shear rotor-stator mixer. The Model VMC-100 includes an air/oil lift that raises the agitators out of the mix vessel. This model is manufactured in several sizes ranging from one through 750 gallons. Optional features including vacuum construction, jackets for heating or cooling, charge ports, controls, etc., are available. (Charles Ross Charles Ross can refer to:
