New mixing and dispersion system combines a Ross high shear mixer and a specially designed PowerMix for use in manufacturing fine dispersions. The two mixers are mounted on a common base and connected with piping to allow continuous circulation of materials until the desired dispersion is achieved. A built-in control panel permits fine control of all agitator speeds, amperage and run times. Software is available to insure that the desired results are achieved repeatedly, batch after batch. The PowerMix includes two high viscosity planetary stirrers, two high-speed dispersers and a scraper to wipe the sides of the vessel.
