ROSS 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. A SLIM mixer assembly with Progressive Spiral Porting™ creates a powerful vacuum that draws powders directly into the high-shear zone and rapidly disperses individual solid particles into the liquid vehicle. This method of powder addition dramatically reduces the formation of lumps (fisheyes), prevents floating powders, eliminates dusting, and accelerates mixing time. It can also be used to introduce minor liquid components and create fine emulsions.
