Triple Shaft Mixer

How it Works

Benefits of choosing a ROSS Triple Shaft Mixer

What does a ROSS Triple Shaft Mixer do?

The ROSS Triple Shaft Mixers are a versatile and highly customizable system for making viscous formulations. They provide agitation and high speed dispersive mixing powerful enough to batch viscous solutions, dispersions, suspensions, and emulsions with viscosities in the hundreds of thousands of centipoise.

How does a ROSS Triple Shaft Mixer work?

The Triple Shaft Mixer includes an anchor agitator, a high shear rotor/stator mixer and a high speed disperser. The rotor/stator has the ability to emulsify and homogenize, while the open disc blade of the disperser is designed to induce vigorous turbulent flow and create a vortex into which dry ingredients can be poured for fast wetting. The anchor feeds product towards the high speed agitators and ensures that the mixture is constantly in motion. Teflon scrapers can be installed on the anchor

Why Choose a ROSS Triple Shaft Mixer?

  • product feature

    Design – Made of high-quality stainless steel type parts, these machines are built for robust and continuous use. Precision bearings with large bearing spans minimize deflection and vibration of agitator shafts. This contributes to improved strength and longevity of the robustly designed agitation system.

  • product feature

    Safety - Safety limit switches prevent operation of the mixer when the mix vessel and/or agitators are not in the mixing position. Motors, control panels and all electrical components are customized to meet area classification requirements.

  • product feature

    Independently Driven Agitators – The agitator system is highly customizable in terms of blade combinations and designs. No bearings or seals are submerged into the product zone which means better protection against contamination.  

  • product feature

    Change Can – Designed for use with multiple interchangeable vessels.  Triple-Shaft Mixers up to 1000 gallons are supplied with an air/oil lift system. Another advantage to the change can design is the ability to use a Discharge System for fast transfer of the finished product, higher yield and easier cleaning.

  • product feature

    SLIM Powder Induction – Triple-Shaft Mixers 4 gallons and larger with a rotor/stator assembly can be outfitted with the ROSS Solids/Liquid Injection Manifold (SLIM) Technology which generates an intense vacuum in the high shear zone and inducts powders sub-surface.

      • Multi-viscosity mixing in a Triple-Shaft Mixer

        This bulletin provides a step-by-step look at a typical multi-shaft mixer application which demonstrates the system`s processing flexibility in terms of mixing, heating, cooling and deaerating batch material at different viscosity stages.

      • Shorten your dissolution time by switching to a multi-agitator mixer.

        Dissolution processes can be optimized through the use of multi-agitator mixers which provide a combination of low-speed blending, high shear mixing, particle size reduction and superior heat transfer.

      • Rethink your reactor design

        Chemical processes accomplished in conventional stirred tank reactors can be optimized by switching to a multiagitator system capable of high speed dispersion or dissolution, as well as superior heat transfer and efficient turnover even at elevated viscosities.

      • Multi-purpose laboratory mixers

        Multi-Shaft Mixers are highly efficient and versatile equipment ideal for developing formulations of wide ranging viscosities and characteristics.
