Charles Ross & Son Company VersaMix


The Charles Ross & Son Company Ross VersaMix is a multi-shaft mixer designed for viscous applications requiring a high level of accuracy and batch-to-batch consistency. In a VersaMix, two or three independently driven agitators work in tandem to ensure high-speed fine dispersion, efficient turnover and uniform heating/cooling.

Shown is a Ross VersaMix Model VMC-200 with 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 2” thick mineral wool and sheathed with water-tight stainless steel cladding.

Equipped with a 10HP anchor agitator, 20HP disperser and 25HP rotor/stator, the VMC-200 delivers a robust combination of laminar bulk flow and shear intensity necessary for homogenization and deagglomeration in high viscosity conditions up to several hundred thousand centipoise. The vacuum cover includes multiple charging ports, viewing windows, tank light and a thermoprobe. Finished product is discharged out of a 3” pneumatically-actuated diaphragm valve installed on the tank’s conical bottom.

Available in standard sizes from one through 4,000 gallons capacity, the Ross VersaMix offers simple and reliable scalability from product development all the way to full scale production. Mixer features are tailored to a specific formulation or range of products for maximum functionality. Charles Ross & Son Company offers a trial/rental program and free-of-charge mixer demonstration/lab testing services.
