Rotor-Stator type High Speed Mixer is a standard inline rotor-stator mixer that provides higher shear through large number of shearing events to provide narrow particle size distribution. The High Speed Mixer mixes through a rotor-stator array in single or multiple passes. The High Speed Mixer exhibits high performance under all industrial environments. The Rotor-Stator type High Speed Mixer enables sub micrometer particle distribution with the help of ultra high shear technology.
