Inline High Shear Mixers

How it Works

Benefits of choosing a ROSS Inline High Shear Mixer 

What does a ROSS Inline High Shear Mixer do?

The ROSS Inline High Shear Mixer is ideal for reducing the size of particles and droplets in fine dispersions and emulsions to create scalable, highly repeatable products.

How does a ROSS Inline High Shear Mixer work?

The ROSS Inline High Shear Mixer design consists of a single, dual or four stage rotor that turns at high speed within a stationary stator. As the rotating blades pass the stator, they mechanically shear the contents.

Why Choose a ROSS Inline High Shear Mixer?

  • product feature

    Design - An inline rotor/stator mixer behaves like a centrifugal pumping device. Because an inline mixer is typically positioned on the floor or on a platform below the liquid level, gravity usually feeds the product into the mix chamber. Here the product is subjected to high shear as the rotor turns at tip speeds ranging from 3,000 to 4,000 ft/min and expels the mixture out of the chamber through the holes of the stationary stator. Depending on the rotor/stator geometry, an inline mixer can handle viscosities up to 10,000-20,000 cP without external pumping assistance. With an auxiliary pump, it can process much more viscous materials.

    Flexibility – Many batch mixing processes can be optimized with the addition of an inline rotor/stator mixer. The supplemental agitation and shear provided by an inline mixer boosts production by reducing cycle time. Multiple batch tanks can be serviced by a single inline mixer and benefit from its pumping capabilities. Another practical advantage to an inline mixer is that it is easily installed without disturbing pre-existing equipment.

  • product feature

    Scalability – ROSS Inline High Shear Mixers are available from bench top laboratory models to very large production models capable of dispersing several thousand gallons at a time. Inline models are supplied in many sizes from 1 through 100 horsepower in standard, chemical-duty and sanitary 3A-approved designs.

  • product feature

    SLIM – ROSS offers a dedicated series of Inline High Shear Mixers with Solids/Liquid Injection Manifold (SLIM) Technology. The SLIM rotor/stator generates an intense vacuum in the high shear zone and sucks in powders into the fluid stream. Since solids and liquids are combined at the exact point where intense mixing takes place, the SLIM is capable of handling extraordinarily large volumes of solids without clogging or agglomerates.

      • Run your rotor/stator mixer at maximum speed to optimize particle size reduction.

        Generally, the maximum speed setting of a rotor/stator mixer provides the optimal mixing results in terms of particle or droplet size reduction. Once an equilibrium size distribution is reached, subsequent passes through the rotor/stator give diminishing returns. For applications that are processed at the maximum speed of a traditional rotor/stator mixer but still fall short of the desired particle or droplet size, a move to higher energy devices, such as ultra-high shear mixers, is recommended.

      • Selecting the best rotor/stator combination for your batch process

        The batch rotor/stator mixer is an integral part of many manufacturing processes with various styles and models available in the market today. Determining the most suitable mixer configuration for your particular application is important in ensuring process-line efficiency and consistent finished product quality..

      • High Speed Mixing: Saw-tooth Dispersers vs. Rotor/stator Mixers

        The saw-tooth disperser and rotor/stator mixer are two of the most widely used high speed mixers yet many are unaware of the differences in their utility and operating capacities. Knowing the unique attributes of these devices is important in mixer selection and process optimization.
