The Ross PowerMix Planetary Dispersers with PLC Recipe Controls from Ross, Charles & Son deliver batch-to-batch consistency in the mixing of high-solids, high-viscosity applications.

The Ross PowerMix Planetary Dispersers with PLC Recipe Controls from Ross, Charles & Son deliver batch-to-batch consistency in the mixing of high-solids, high-viscosity applications. Two independently-driven agitators--a high-speed sawtooth disperser and a low-speed planetary stirrer--make the PowerMix suitable for dispersing powders and applying high shear to viscous materials without the risk of localized overheating.

The Ross Model PDM-40 PowerMix (pictured) has a working capacity of 40 gallons. The system is rated for vacuum up to 29.5 in hg and includes a built-in liquid ring vacuum pump. All wetted surfaces are stainless steel 316 L polished to 150-grit finish. The 10HP rectangular planetary stirrer and 15HP dual-blade disperser revolve around the batch while rotating on their own axes at variable speeds. A sidewall scraper arm and bottom scraper attached to the planetary stirrer enhance heating/cooling via the jacketed vessel. A hot water temperature control unit can be supplied with the PowerMix.
