The PreMax is a highly efficient shear mixer, used to improve dispersion prior to milling. The PreMax contains a specially designed rotor/stator that creates high flow and shear rates. According to the manufacturer, the PreMax has proven that it can in some cases eliminate the need for added secondary processing. In all cases, this mixer reduces the number of passes required to obtain high quality dispersions by up to 50 percent of that which is normally required. The PreMax is available in a wide range of sizes up to 200 hp. The PreMax is also offered as a component of dual or triple shaft mixers. Most units are constructed in stainless steel, are provided with air/oil hydraulic lifts and include variable speed drives.
