Information on how to select a portable mixer for a relatively small mixing,  blending, dilution (dissolving), or basic heat transfer for volumes up to 15,000 gallons.  Determine the volume (gallons) of fluid to be mixed.  Next, to select your portable mixer, determine the viscosity and refer to the tables (charts) below.  We have listed below a table of typical viscosities for various liquids for comparison.  If you have difficulty determining or estimating your fluids viscosity, call us for an evaluation of your application.  The numbers represent the recommended horsepower for the specific application. "D" stands for direct drive models and "G" stands for gear drive models. For more vigorous agitation, choose the next size larger machine than the recommendation.

mixerinformation.org was established to provide a source of mixing information about common and specific mixing processes.  Discussions ensue about mixer designs, mechanical concepts in regard to mixers, mounting orientation and configurations.  We also review typical mechanical design concepts that can lead to mixer failure.  The mixing information discusses the use of static mixing or plug flow mixing versus batch or continuous stir flow designs.  Waste and water treatment cover applications such as flash or rapid mixing, floc or flocculation using a flocculator, lime make-up and storage, water treatment chemical make-up, polymer or polyelectrolyte day tanks, magnesium hydroxide storage.  Other useful mixing performance topics are also discussed, such as the counter intuitive results of using the G-Factor as the prime factor of design.
