Multi-agitator system for mixing and dispersion

| By Mary Bailey


Charles Ross and Son

The 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. The VersaMix Model VMC-200 has a maximum working capacity of 200 gal. 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-in. thick mineral wool and sheathed with water-tight stainless steel cladding. Equipped with a 10-h.p. anchor agitator, 20-h.p. disperser and 25-h.p. 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-in. pneumatically actuated diaphragm valve installed on the tank’s conical bottom. — Charles Ross and Son Co., Hauppauge, N.Y.
