Double Planetary Mixers
Ross has been the innovator and leader in Double Planetary Mixer design for 50 years. Well suited for mixing high viscosity materials, Double Planetary Mixers can be optimized for operation in many industries. double planetary mixer In a Ross Double Planetary Mixer, two planetary blades 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.

In only 36 revolutions, the Double Planetary Mixer's blades have touched virtually the entire batch. It only takes a few minutes for the blades to completely mix a batch and by preventing a layer from forming on the periphery, the blades ensure efficient transfer throughout the batch. Three different blade types are available:
  • Rectangular blades - Appropriate for most applications. They are the proven choice for many low to high viscosity mixing applications.
  • Finger Blades - Specialty blades optimized for mixing delicate solids and fibers.
  • New HV Blades - Patented high viscosity blades for ultra high viscosity materials. Stops materials from "climbing up" the blades.

    The new high viscosity blades for ultra high viscosity applications allow the Ross Double Planetary Mixer to be used in place of Double Arm Kneaders. Advantages of the Ross Double Planetary Mixer compared to Double Arm Kneaders include:
    • Less expensive
    • Requires less maintenance
    • No packing glands or bearings submerged in the product zone
