High-Shear

High-shear impellers convert the majority of the energy of the motor to shear force. These kind of blades - also known as cowles mixer blades - excel at quickly breaking down solids and producing a fine grind. MixerDirect uses three grades for its high-shear blades: the HFD which includes vanes for increased pumping, allowing it to do higher viscosities, the DBL which is a standard design used in the paint industry for many years, and the USB, a brand-new design to get even more shear out of a single high-speed impeller blade.  

Stiffening plates can be used in conjunction with dispersion blades to increase blade life. Our bolt-on hubs, weld-on hubs, and blade adapter shaft allow for easy installment of all high shear dispersion blades.

Ultra Shear Dispersion Blade, 4in Dia, 3/8in CH

Ultra Shear Dispersion Blade, 4in Dia, 3/8in CH

USB040037 $76

Ultra Shear Dispersion Blades rotate at high RPMs to facilitate the quick impartation of solids at a fine grind. The liquid contacts the blade and moves outward to to flow over the teeth breaking the agglomerations into increasing smaller particles. The Ultra Shear Blade includes extra surface area at the blade tip to facilitate even higher levels of shear in the product. This leads to even faster throughput! Typically used in paints and inks, they are now being used in a variety of industries for increased efficiency.

High Flow Dispersion Blade, 4in Dia, 3/8in CH

HFD040037 $110

Dispersion Blades rotate at high RPMs to facilitate the quick impartation of solids at a fine grind. The liquid contacts the blade and moves outward to to flow over the teeth breaking the agglomerations into increasing smaller particles. Most Dispersion blades have issues realted to sufficient fluid motion to get a batch to complete uniformity. Mixer Direct addresses that problem with the HFD line. Each blade has axial flow blades integrated into the geometry of the blade, providing extra flow for higher visocosity applications. Typically used in paints and inks, they are now being used in a variety of industries for increased efficiency.
