ROSS: Dual Disperser
This company recently announced the addition of an advanced planetary mixer. The new 4-gal planetary dual disperser (Model PDDM-4) is equipped with two high-viscosity blades and two high-speed dispersers; all four agitators rotate on their own axes while orbiting the vessel, for rapid powder wet-out and deagglomeration. This product is designed for vacuum operation and includes a jacketed mix vessel. The PDDM reportedly delivers dispersion and uniformity throughout a wide viscosity range up to around two million cp.
The PDDM-4 is one of over 40 mixers and blenders showcased at the Ross T&D Center. A typical mixing simulation test uses the end user’s actual raw materials and the mixer is operated at process conditions as close as possible to actual production. Proof-of-concept demonstrations such as high shear emulsification, particle size reduction, dry blending, vacuum drying, high viscosity mixing and three roll milling are reportedly performed routinely.
