Charles Ross & Son: VersaMix Multi-Shaft MixerVice President, Sales Chris Ross announced the new Sanitary VersaMix Multi-Shaft Mixer. Pictured is a typical 300-gallon Sanitary VersaMix. Throughout the pharmaceutical industry, the VersaMix is well-proven equipment for the processing of viscous formulations including suspensions, pastes, slurries, gels and emulsions.
This mixer design is composed of three independently-driven agitators working in tandem. The high speed disperser quickly draws powders into the liquid batch through a powerful vortex. The rotor/stator carries out a number of tasks depending on the product being mixed - it can break down agglomerates, accelerate homogenization, or prepare fine droplets in an emulsion. Finally, the low-speed anchor promotes bulk flow and uniform batch temperature while scraping the vessel sidewalls and bottom.
Sanitary designs standardize on stainless steel 316 wetted parts polished to 150-grit finish or higher. Popular optional features include vacuum-capability, clean-in-place spray nozzles, temperature probes, interchangeable jacketed mix vessels, powder induction capability (available on special design rotor/stators), sight/charge ports, control panels and PLC systems. Offered in many sizes from 1 through 4000 gallons capacity. Units are available for no-charge mixing trials at the Ross Test & Development Center. Trial/Rental units are also in stock.
