Dispersion Blades

Dispersion Blades

The high-speed disperser uses a disc-style agitator blade or dispersion blade. The main function of dispersing is not performed at the disc but as the product leaves the blade. To produce the laminar flow for dispersion, these blades must produce a horizontal discharge of the product. It is therefore important to ensure the disperser shaft is vertical. Dispersion blades are fitted with either alternating teeth or grooves. These features result in a rapid shift of brief over-pressure and under-pressure zones. The rapid alternating pressure zones aid in the wetting and mechanical separation of the pigments. The size of these teeth contributes to the flow generated by the impeller. 

Shear Blades

These are good starting points for most dispersion operations.  The F-Blade is the most common blade in use.  The common feature of these shear blades is low profile alternating teeth.

Pumping Blades

The pumping blades or high vane blades provide less shear and more flow for better blending. Increasing turbulence is produced by their higher tooth profile.

Mixed Flow

The Mixed Flow blades are an excellent choice for fibrous materials and dissolving of solid resins

Louver Blades

The Louvered Blades add a vent or cup to the blade to introduce an axial flow component.

Ring Blades

For the toughest to grind pigment dispersions, these ring blades provide the highest shear of any dispersion blade

Axial Flow

These fan-style blades produce the largest axial flow component.

Polymer Blades

To avoid metal contamination and improve wear performance we offer Urethane, UHMW, and other polymer blades.

Our disperser blades can be bored to fit any of the common dispersers including Myers Mixers, Morehouse Cowles, Hockmeyer Dispersers, Schold, Schar, etc. 

These impellers find use in many chemical processing industries including paint, coating, adhesive, cosmetic, pharmaceutical, etc.
