How it Works
Benefits of choosing a ROSS Inline Ultra High Shear Mixer
What does a ROSS Inline Ultra High Shear Mixer do?
Available in three ultra-high shear rotor/stator designs – the X-Series, QuadSlot and MegaShear -- ROSS Inline Ultra High Shear Mixers are ideal for reducing the size of agglomerates and droplets in very fine dispersions and emulsions superior to those produced by conventional multi-stage rotor/stators and colloid mills. Sample applications include adhesives; cosmetics and personal care products (creams, lotions, sunscreen, soaps, deodorant, hair products, etc.); flavor emulsions, condiments, salad dressing, sauces and spreads; gum dispersions; greases and lubricants; latex emulsions; nanoparticle dispersions and composites; petroleum and biodiesel applications; pharmaceutical emulsions and suspensions; pigment dispersions; electronic inks and battery slurries; specialty coatings and chemicals.
How does a ROSS Inline Ultra High Shear Mixer work?
The ROSS Inline Ultra High Shear Mixer is comprised of an advanced precision rotor that turns at tip speeds of up to 15,000 feet per minute. The material begins at the center of the generator and moves outward through radial channels cut in the rotor/stator teeth. Tolerances are extremely close, and the shear applied to the material in each pass is extraordinarily intense.

Why Choose a ROSS Ultra High Shear Mixer?
Design - An inline rotor/stator mixer behaves like a centrifugal pumping device. The combination of very high tip speeds and extremely tight tolerances between interlocking channels produces emulsions and dispersions that would otherwise require a more expensive colloid mill or high pressure homogenizer. The X-Series and MegaShear are both patented designs.
Scalability – Inline Ultra High Shear Mixers are available from laboratory models to very large production models (10 HP to 200 HP, in both sanitary and industrial configurations.
Flexibility – Many batch mixing processes can be optimized with the addition of an inline rotor/stator mixer. The supplemental shear provided by an Inline Ultra High Shear 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.
Continuous Processing – High performance double mechanical seals, heavy-duty roller bearings and bearing oil cooling system are standard features that allow production-scale Ultra High Shear Mixers to operate continuously.

Ultra-high shear rotor/stator systems speed up cycle time by reducing the number of passes required through a high pressure homogenizer, an inherently low-throughput, high-energy device. Since homogenizers are also generally maintenance-intensive, an efficient â€˜pre-mixerâ€™ generates significant savings in the overall cost of production. In certain applications, ultra-high shear mixers even effectively replace homogenizers..
Consider updating your batch mixing process with an ultra-high shear rotor/stator device. This cost-effective upgrade will deliver finer dispersions, solutions and emulsions at viscosities outside the normal range of conventional rotor/stator mixers. Other benefits include reduced cycle times and more efficient powder additions.
Ultra-High Shear Mixers are ideal for high volume deagglomeration requirements, offering greater throughput, easier clean-up and more convenient maintenance compared to traditional colloid mills, media mills, immersion mills and high pressure homogenizers.
The droplet size distribution of an emulsion largely dictates its stability. Fine droplet sizes are produced by applying sufficient shear, often through the use of conventional rotor/stator mixers. Today, ultra-high shear rotor/stator designs are available which can improve emulsion stability of certain formulations.
