NEXGEN™ Vacuum Rotor Stator: Pure Dispersion

This innovative RotorStator design produces an airless ultra-fine dispersion using an aggressive multi-prong approach to particle size reduction.

Bridging the gap between milling and dispersion, the NEXGEN™ Vacuum Rotor Stator was designed for maximum dispersion. This innovative design with integrated vacuum delivers fast & pure dispersion — NO AIR, NO FOAM… 100% PRODUCT.

The process takes place in a temperature-controlled environment to preserve formulae characteristics and function.  A thorough cooling system covering the chamber and return lines quickly mitigates the heat generated by the aggressive shear forces. The result is a deaerated dispersion, a narrow particle size distribution band, volumetric accuracy, and an optimal dispersion pre-mix for milling into the nanoparticle size range. It easily hooks up to your existing process tanks.  Flexible, portable design.  Easy cleanup and changeovers.

• Vacuum: The air inside the agglomerates expands and forces the particles apart, exposing maximum particle surface area. Liquid and resin encapsulate each particle for fast and thorough wetting.
• Controlled Cavitation: The rapid pressure change inside the vacuum chamber creates micro vapor cavities in the liquid. When these short-lived vapor cavities (bubbles) collapse, they generate a shockwave through the feedstock that further aids in particle size reduction.
• Extreme Shear Zone: The Interlocking ‘H’ Stator Design creates a unique shear pattern of vertical and horizontal slots for ultra-dynamic impact while offering maximum open area for the greatest flow. The tight tolerances between the rotor and the stator create a short distance between particle acceleration and point of contact for the greatest shattering effect on agglomerates.
• Dual Pumping Rotor Design: The product is pulled from both the rotor’s top and bottom, doubling the number of collisions per particle.
• High-speed Recirculation: ~300 gpm. The feedstock is recirculated through the shear zone at high velocity to maximize the number of passes for every drop.
• Powder Incorporation: Direct powder incorporation into the liquid stream using an eductor that controls the flow and creates a venturi effect.  This generates suction at the bottom of the funnel pulling powders into the flow. The high-speed jet coming out of the eductor mixes the powder and liquid before it reaches the rotor-stator.
