Ross has expanded its line of Planetary Dual Dispersers (PDDM), offering more sizes of this powerful mixing system designed for high-viscosity and high-solids applications. These hybrid planetary mixers are comprised of four agitators — two planetary stirrers and two high speed dispersers — all rotating on their own axes while orbiting the mix vessel on a common axis. Pictured are two 200-gallon PPDM’s which can also function as a classic Double Planetary Mixer as the dispersers are easily removable for extreme flexibility.
