One key innovation now being offered on the PreMax is the Solids/Liquid Injection Manifold (SLIM) Technology which allows operators to draw powders straight from the bag and inject them sub-surface at precisely the location where intense mixing takes place. The improved PreMax is equipped with a modified Delta rotor/stator which generates its own negative pressure and does not rely on an external eductor or pump to induct powders.
Complete wet-out and dispersion is virtually instantaneous, even with powders that would, upon contact with liquid, normally form tough lumps or “fish eyes” such as gums, fumed silica and other thickeners. Airborne and floating powders are also eliminated which contributes to faster mixing, reduced waste, safer working conditions and easier clean-up. The operator can simply dip a wand into bulk bags or containers and conveniently induct lightweight powders without creating a dusty environment. A valve on the wand modulates the rate of powder induction.
