A 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 enable the 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 ensure that the desired results are achieved 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. The variable-speed (11-110 rpm) planetary blades are driven by a 1 1/2 HP motor and the variable-speed (900-9000 rpm) high-speed dispersers by a 3 HP motor. The separate high-shear rotor-stator mixer is driven by a 1 HP variable speed motor for operation up to 10,000 rpm.

All wetted parts of the system are constructed of 304-stainless steel and finished to a 320-grit finish to allow for easy cleanup between batches. The system is built for vacuum operation to 29.5 in. Hg and includes a vacuum pump. The mix vessel is jacketed for 50 psig and includes a thermocouple to monitor batch temperature. A discharge valve is provided to discharge the materials on completion of the batch. Additional sizes are available from the 2-gal design to 750-gal production sizes.
