The Ross PreMax is a batch-style rotor/stator mixer designed for ultra-high-shear conditions and vigorous flow. 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, is now offered. It is now 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. E-mail
