The VersaMix Multi-Shaft Mixer, from Ross, Charles & Son, is used to mix pastes, creams, and gel-type products, with capabilities including powder dispersion, emulsification, dissolution, deagglomeration, homogenization, heating/cooling, and deaeration. All these functions are achieved in a closed system, without any transfer steps. The 10-gallon Ross VersaMix Model VMC-10 rated for 29.5 in Hg vacuum up to 15 psi internal pressure. The mixers three-wing anchor (3HP), high speed disperser (3HP), and high shear rotor/stator (3HP) operate independently at different speed ranges to deliver uniformity in low to high viscosity conditions up to several hundred thousand centipoise. All product contact surfaces are stainless steel type 316L polished to 180 grit finish. The mixer cover includes multiple ports for charging raw materials and installation of a vacuum/pressure transmitter, thermoprobe, and tank light. It mates with a jacketed cone-bottom vessel that is designed for 100% discharge through a flush diaphragm valve. A 23-in clearance from the valve outlet to the floor allows operators to position a bucket under the vessel to catch finished product after the mixing cycle.
