Dispersion Rules of Thumb

3827 Views 0 Liked
Posted on: 09/26/2014
 
  • The blade diameter should be roughly 1/3rd the diameter of the vessel.
  • Normal blade is speed is targeted at 5200 fpm (feet per minute).
  • Typical disperser power requirements are in the range of 10 HP per 100 gallons of product.
  • Position blade 1/2 of the blade diameter off the tank bottom
  • Liquid level should be 1 1/2 blade diameters above the blade
  • Blade should be centered in the tank
  • Allow for product vortexing to prevent material from splashing over the top of the tank. 20% freeboard is recommended.

Dispersion RatiosDispersion Ratios

While the above "Rules of Thumb" present a very good starting point, this should not be the sole consideration in specifying dispersion power.

More detailed information can be found on the following pages.  We also offer a Horsepower Calculator to assist in your disperser sizing.
