ROSS: Batch High-Shear Mixers for Fine Dispersions and Emulsions

Ross reports that its batch high-shear mixers equipped with solids/liquid injection manifold (SLIM) technology deliver powders in an efficient manner for quick wet-out and complete dispersion into low-viscosity liquids. In a conventional rotor/stator mixer, materials are continually drawn from below the mixing head and then expelled at high velocity through the stator openings. A SLIM mixer assembly with Progressive Spiral Porting™ reportedly creates a powerful vacuum that draws powders directly into the high-shear zone and rapidly disperses individual solid particles into the liquid vehicle.
According to Ross, this method of powder addition dramatically reduces the formation of lumps (fisheyes), prevents floating powders, eliminates dusting, and accelerates mixing time. The SLIM can also be used to introduce minor liquid components and create fine emulsions.
To easily raise and lower the high-shear mixer in and out of the mix vessel, Ross offers a floor-mounted design equipped with an air/oil hydraulic lift. Safety limit switches prevent operation of the mixer while in a raised position or without a mix vessel in place.
