How to Choose Your Dispersion Blade Style

All blade designs generate similar shearing energy, which is the hydraulic tearing apart of particles. C design blades shear slightly less and generate less heat than the others due to the lower number of teeth per blade.


  • - Performance match for the Cowles blade
  • - Our most popular dispersion blade
  • - Used in manufacturing paint, clay slurries, paper, coatings, ink and more
  • - Rugged and efficient design
  • - Economical to use


  • - Performance match for Hockmeyer "F'
  • - Rectangular teeth, uniform size and height
  • - Popular all-around blade


  • - High-vane blade produces high pumping action
  • - Effective for heavy-bodied and/or heat-sensitive thixotropic materials


  • - Blade for high vehicle viscosities and high-solids loadings
  • - Creates great turbulent flow with good shear and laminar flow
  • - Teeth vary in height and angles of attack
  • - Intermediate teeth set to assist flow feeding others
  • - Great blade dispersion with high pumping rate


  • - Has a knife style tooth extending out from the blade
  • - Unique blade style for maximum cutting
  • - Alternation vertical teeth ideal for cutting or shredding rubber, waxes, or other soft gummy materials

Pumping Capacity: Refers to how well it moves material around the vessel or turns batch over. Good pumping action is related to the size and shape of the teeth. A & E provide lower pumping capacity. B, C, and D provide higher pumping capacity.

Dispersing Viscous Material: Blades C & D are recommended for dispersion of viscous materials due to higher pumping capacity required. This also requires higher horsepower, so avoid overloading the motor.
