Ross manufactures Double Planetary Mixers for heavy-duty mixing of viscous formulations up to around 6 million cP. Many processes that used to rely on horizontal sigma blade mixers (kneaders) are now routinely produced in change-can Ross Double Planetary Mixers. A great advantage to this vertical mixer design is the absence of any shaft seals, bearings, packing glands or stuffing boxes in the product zone. In addition, the agitators are raised and lowered in/out of the mix vessel by a hydraulic lift, enabling easy access for cleaning between batches. Mix vessels are interchangeable and can be dedicated to a particular formulation, further reducing the risk of cross-contamination.

Pictured is a 10-gallon Double Planetary Mixer equipped with the classic rectangular stirrer blades, a vacuum-rated and jacketed mix vessel, tank light, pre-wired control panel and a rotating RTD thermoprobe for accurate measurement of batch temperature. This particular unit is used for heavy-duty mixing of advanced composites and adhesives.

The following optional features are commonly supplied on Ross Double Planetary Mixers:

  • Charge and sight ports
  • Vacuum and/or internal pressure design
  • High Viscosity "HV" blades
  • Removable sidewall scraper arm
  • Bottom scraper blades attached to the planetary stirrers
  • Heating/cooling jacket
  • Sheathing and insulation
  • ASME code stamp can be provided, as needed.
  • Sanitary design
  • Special polishes and coatings
  • Built-in vacuum pump
  • Operator stations and PLC systems
