Solids/Liquid Injection Manifold

December 20, 2011

The Ross Solids/Liquid Injection Manifold (SLIM) is a high shear mixer system designed to accelerate the dispersion of hard-to-wet-out solids while eliminating floating powders in batch tanks and reducing dusting in the mixing area. Powders like fumed silica, CMC, guar gum, carbon black, carrageenan, xanthan gum, talc, pectin, flours, clays, carbomers and other rheology modifiers can now be mixed into liquids quickly and economically, requiring no filtering step after the mixing operation. Compared to other powder injection systems that rely on an external vacuum pump to establish vacuum in the mix vessel, the SLIM system utilizes a specially engineered rotor/stator assembly that generates its own powerful vacuum to draw solids sub-surface. This method of powder induction allows the operator to inject powders at a fast but controlled rate for highly repeatable and superior dispersion results.
