HIGH SHEAR HOPPERSThe shear hopper diffuses additives into your materials by means of high velocity, suction, turbulence and recirculation.  Additives can be added manually and liquids can be added from a drum or tank. It requires fewer polymer or surfactant and up to 50% less bentonite.  The PSI shear mixer is both a radial premixer — eliminating clumping, fisheyes and microgel — and mixing eductor — providing vigorous mixing and robust shearing.
