What does a ROSS PreMax do? A batch-style ultra-high shear device, the ROSS PreMax was engineered to address the limitations of rotor/stator mixers when processing higher viscosity products over 20,000 cP, or products requiring an extremely fine particle or droplet size distribution. How does a ROSS PreMax work? The ROSS PreMax is a patented (US Patent No. 6,000,840), top-entering batch mixer with Delta ultra-high shear rotor/stator technology. The Delta rotor is specially contoured for high pumping capacity and shear intensity. Product is drawn from above and below the rotor, then expelled radially through the stator slots at high velocity. This generates upper and lower vortices allowing for extremely efficient powder additions and rapid turnover rates. Very fine droplet sizes are achieved while solids are quickly wetted out instead of floating on the liquid surface. Design - The PreMax is typically used as a stand-alone unit and does not require supplemental agitation for products up to 50,000 cP. For higher viscosity products, it is supplied in a multi-shaft mixer arrangement equipped with an anchor agitator. STANDARD FEATURES: Driven by an explosion-proof motor designed for 230/460 volt, 3 phase, 50/60 Hz. Mixing head hydraulically raised by an air/oil hydraulic lift. Patented Delta rotor and stator. Stainless steel type 316 wetted parts polished to an 80-grit finish. Stellite rotor shaft bushing and shaft wear sleeve. All non-stainless steel external surfaces coated with a two-part acrylic urethane enamel paint. Clamping device to secure mix vessel. Safety limit switches to prevent operation of mixer while in the raised position or without a vessel in place.
