Charles Ross Introduces Solids/Liquid Injection Manifold High Shear Mixer System


The Ross Solids/Liquid Injection Manifold (SLIM) is a high shear mixer system designed to prevent the formation of agglomerates and "fish eyes" in thickened solutions. This novel method of powder induction utilizes a specially engineered rotor/stator assembly that generates a powerful vacuum for drawing solids into the mix chamber. The liquid stream enters the mixer and immediately encounters the powder addition under intense shear conditions. The resulting dispersion is expelled centrifugally through the stator openings at high velocity. Stubborn agglomerates and "fish eyes" are prevented from forming. The sub-surface addition of solids also eliminates the occurrence of floating powders in batch tanks.

A "hose & wand" attachment to the powder inlet of the SLIM allows operators to conveniently draw lightweight, free-flowing powders straight from within the bulk container. For faster induction rates, solids are loaded into a hopper located right above the mix chamber.

Shown is a 3-A certified, 25HP portable inline SLIM unit with hopper attachment. At the end of a cycle, the mixer is easily cleaned in place and moved to a different tank. Other installations hard-pipe the inline mixer to multiple batch tanks and simple valves are used to divert finished product downstream or switch instantly from our source vessel to another. Inline SLIM mixers eliminate the need for an auxiliary pump in most applications. The Ross SLIM technology is also available on batch style rotor/stators.
