High Shear Models

Ultra High Shear Mixers
The high tip speeds and complex turbulent mixing patterns generated within the rotor/stator assembly of an ultra-high shear mixer enable it to produce fine emulsions and dispersions. The benefit of preparing a higher quality pre-mix lies in the reduction of passes through the high pressure homogenizer, an inherently low-throughput device. A greater volume of end product can therefore be produced per operating hour of the homogenizer. Being an inline device, the ultra-high shear mixer can mix raw materials and pump the mixture directly to the homogenizer. Flowrate is comparatively higher than a similarly powered homogenizer.

Special Ultra High Shear designs include
Multi-stage design - These include two or four rows of rotating blades that nest inside a matching stator. The mix material enters through an inlet connection and is accelerated outward by centrifugal force. During each transit through the rotor-stator, the material is subjected to a succession of increasingly intense shearing events -until it finally exits downstream, or is recirculated for another pass through the mixer. Uniform droplets below 1 micron are possible using these designs.

Low Profile X design - The X-Series rotor and stator is comprised of many concentric rows of intermeshing teeth. Tolerances are very close, and the shear rates are extremely high. This unit operates at tip speeds up to 18,000 fpm. The X is a great choice for emulsions and dispersions that would otherwise have required more expensive homogenizers or colloid mills.

MegaShear design - The MegaShear rotor and stator is of a unique design, consisting of opposed, semi-circular, cylindrical grooves that are machined on both the rotor and stator faces. When a fluid is exposed to these opposed partial cylinders, a counter-flow is induced which splits and redirects the flow of the fluid upon itself to create an extremely high-turbulent collision phenomenon.
