Charles Ross Promotes Ultra-High-Shear Mixer

The company says that the unique geometry of the Delta rotor/stator generator results in accelerated dispersion and rapid turnover rates.

Charles Ross & Son Co. (Hauppauge, NY) is promoting the Ross PreMax ultra-high-shear mixer featuring patented “Delta” rotor/stator assembly.

The company says that the unique geometry of the Delta rotor/stator generator produces a double vortex that draws batch material from both the top and bottom of the mixing chamber. This results in accelerated dispersion and rapid turnover rates. The mixer runs at a maximum tip speed of 5,000 fpm and can handle viscosities of up to 50,000 cP.

The company says that compared to other batch-style mixers, including high-speed dispersers, traditional rotor/stator mixers, and immersion mills, the PreMax mixer can achieve superior particle-size reduction. In addition, the firm says that based on side-by-side tests, the PreMax can finish viscous emulsions up to six times faster than ordinary high-shear mixers.
