The Double Planetary Mixer includes two blades that rotate on their own axes, while they orbit the mix vessel on a common axis. The blades continuously advance along the periphery of the vessel, removing material from the vessel wall and transporting it to the interior. After one revolution the blades have passed through the entire vessel, after three revolutions most materials have been mixed and after only 36 revolutions, the blades have contacted virtually the entire batch.

Ross pioneered Change Can mixer design nearly 100 years ago. Today we offer many of our mixers including our PowerMix with this option, which can dramatically increase production in your plant. While one vessel is wheeled away for remote discharge and cleaning, another wheels into place to start the next batch immediately.

Ross Planetary Mixers have been the world's leader for the last 50 years. Today it still surpasses all others in both productivity and long-term reliability. With no packing glands or bearings in the product zone, contamination is virtually eliminated.

This mixer is ideal for mixing and kneading viscous pastes or putty-like materials. Capacities from 1/2-pint through 400 gallons. A wide variety of options include vacuum/pressure, thermal jacketing and sanitary designs.

STANDARD FEATURES:

• Full vacuum change can design
• 1/2Pt, 1Pt and 1Qt models: air/oil hydraulic lift raises and lowers the mix can to and from the mixing position.
• 1 to 5 gallon models: air/oil hydraulic lift lowers and raises the agitators to and from the mixing position.
• Integrated base design for mounting on table top or work bench
• Rectangular stirrers or High Viscosity “HV” blades
• Agitator drive components and lift system are fully sheathed
• Stainless steel type 304 wetted parts with 80 grit polish
• Non-stainless steel components are finished with a durable two-part epoxy coating
• TEFC 230/460 volt, 3 phase, 60 Hz motor
• Stainless steel gearbox with Viton sealing o-rings and lip seals on stirrer shafts
• Safety limit switch to prevent operation of the mixer when the mix vessel or agitators are not in the mixing position

Hybrid planetary mixers are utilized for creating fine dispersions in viscous mixtures, typically within the viscosity range of 100,000 to 2 million cP. Intense mixing is applied to the product by constantly advancing a high speed disperser and a low speed stirrer into the batch. Solids are quickly incorporated into the viscous bulk material and agglomerates are dispersed regardless of product flow characteristics.

Designs for multiple planetary stirrers and disperser blades are available for more demanding applications.

To date, ROSS has supplied over 2,000 of the model PDDM alone for process industries worldwide.

STANDARD FEATURES:

• Full vacuum change can design
• Vertical lift design (reverse lift) for raising of mix can to the operating position
• Integrated base design for mounting on table top or work bench
• Two (2) Rectangular Stirrers or High Viscosity “HV” Blades
• Two (2) High Speed Disperser Shafts and Blades
• Agitator drive components and lift system are fully sheathed
• Stainless steel type 304 wetted parts with 80-grit finish
• Non-stainless steel components are finished with a durable two-part epoxy coating
• TEFC 230/460 volt, 3 phase, 60 Hz motors
• Stainless steel gearbox with Viton sealing O-rings and lip seals on stirrer shaft, disperser shaft and upper gearbox cover
• Safety limit switch to prevent operation of the mixer when the mix vessel is not in the mixing position

The patented PowerMix* combines a planetary blade and a high speed dispersion blade. Both agitators are in constant motion.

The planetary and the high speed disperser blades rotate on their own axes and also rotate continuously around the vessel. The planetary blade feeds materials directly into the high shear zone of the orbiting high speed disperser. This combination of unique mixing actions combine to eliminate the need for multiple mixers that this one machine can accomplish.

Both agitators are independently variable speed to permit users to fine tune the speeds to the process at hand. The PowerMix is available in sizes from 1/2 through 750 gallons and can be supplied with many options such as vacuum/pressure, jacketed vessels, etc.

STANDARD FEATURES:

• Change can design
• Air/oil hydraulic lift for lowering and raising agitators to and from the mixing position
• Rectangular Stirrer and High Speed Disperser
• Agitator drive components and lift system are fully sheathed
• Stainless steel type 304 wetted parts, 80 grit polish
• Non-stainless steel components are finished with a durable two-part epoxy coating
• Totally Enclosed Fan Cooled (TEFC) motors designed for 230/460V, 3ph, 50/60Hz
• Heavy-duty carbon steel gearbox with special gearing
• Safety limit switches prevent operation of the mixer when the vessel or agitators are not in the mixing position.
• Mixer cover is easily removed providing access to upper gearbox area for simple maintenance and cleaning
