The ROSS Double Planetary Mixer is widely used for high-precision mixing, granulation and vacuum drying, but remains the industry authority for rugged applications requiring enormous torque. Patented High Viscosity “HV” Blades work in tandem to knead and mix from a vertical orientation, augmented by large shafts and generous bearing spreads -- an ideal combination for tough-to-mix formulations up to 6 million cP or higher. The robust design includes a heavy-duty fabricated gearbox engineered for extreme stability and smooth planetary movement of the stirrers as they orbit a common axis. These change-can machines are known across many process industries for delivering quick ROI and remaining in service for over 60 years of continuous usage. Shown are two 200-gallon ROSS Model DPM-200.
