The Double Planetary Mixer (DPM) from Ross, Charles & Son can be used for single-pot mixing and deaeration of viscous formulations such as thick pastes, putties, gels, and other semi-solid products.

The Double Planetary Mixer (DPM) from Ross, Charles & Son can be used for single-pot mixing and deaeration of viscous formulations such as thick pastes, putties, gels, and other semi-solid products. The mixer is equipped with high viscosity blades allowing it to process highly filled and high density applications up to six million centipoise in viscosity. This heavy-duty mixer features a high-precision gearbox enabling quiet operation as well as reduced wear and tear. 

The DPM’s stainless steel wetted surfaces are 150-grit finish and electropolished with a dust shield to prevent product dust and splash from getting into the gearbox. The planetary high viscosity blades orbit the vessel at 7 to 30 rpm. Additionally, a detachable sidewall scraper arm is supplied for sticky applications. A dual-post hydraulic lift with safety locking mechanism raises/lowers the agitators to and from the mixing position. The mixer’s change can design allows the use of multiple vessels: two 200-gallon mix cans supplied with the DPM-200 include a 50-psig dual-zone spiral baffled jacket, glass wool insulation, stainless steel sheathing, RTD thermocouple, caster wheels, and tow hitch.
