How to Choose Your Dispersion Blade Style
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.
A.
- - 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
B.
- - Performance match for Hockmeyer "F'
- - Rectangular teeth, uniform size and height
- - Popular all-around blade
C.
- - High-vane blade produces high pumping action
- - Effective for heavy-bodied and/or heat-sensitive thixotropic materials
D.
- - 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
E.
- - 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.
