The Ross VersaMix is a multi-shaft mixer suited for viscous applications requiring a high level of accuracy and batch-to-batch consistency.

The Ross VersaMix is a multi-shaft mixer suited for viscous applications requiring a high level of accuracy and batch-to-batch consistency.

Available in standard sizes from 1- to 4000-gallon capacity, the mixer offers simple and reliable scalability from product development to full-scale production. Two or three independently-driven agitators work in tandem to ensure high-speed fine dispersion, efficient turnover, and uniform heating/cooling. Mixer features are tailored to a specific formulation or range of products for maximum functionality. 

The VMC-200 model has a maximum working capacity of 200 gallons. An air/oil lift raises and lowers the agitators into the vacuum-rated vessel. All product contact surfaces are stainless-steel type 316L polished 180-grit finish. The ASME 60-psi jacket on the vessel is insulated with two-inch thick mineral wool and sheathed with water-tight stainless-steel cladding.

Equipped with a 10HP anchor agitator, 20HP disperser, and 25HP rotor/stator, the mixer delivers a combination of laminar bulk flow and intensity necessary for homogenization and deagglomeration in high-viscosity conditions up to several hundred thousand centipoises. The vacuum cover includes multiple charging ports, viewing windows, tank light, and a thermoprobe. Finished product is discharged out of a three-inch pneumatically-actuated diaphragm valve installed on the tank’s conical bottom.
