How to Assemble Dispersion Blades

INDCO Dispersion Blades

INDCO presents a video guide to dispersion blade assembly. In this video guide, we focus on four types of assemblies in the demonstration: The TS-Series shaft for lab stirrers or drills, the DS-series shafts for any 1/2" chuck, the HS-series adapters and finally, the bolt-on and weld-on hubs. We have 5 dispersion blade types to fit your mixing needs.

  • The Design A blade, our most popular, is widely used as a standard in dispersions, including paints, dye pigments and many more applications. It consists of alternating teeth bent at a ninety-degree angle to provide the high shear required in dispersion applications.
  • Our Design B is also a popular all-around dispersion blade option. Its teeth are more rectangular in shape than those of the A blade.
  • The Design C features teeth shaped similarly to the A, but with much greater height. The additional tooth height increases the pumping action of the blade while still providing high shear.
  • Our Design D blade features the most unique tooth profiles. This blade has teeth similar to the B blade, but they are alternately spaced with specially shaped teeth for the most pumping from a dispersion blade. This is the most aggressive blade option for completing dispersion processes in higher viscosity materials with a single blade setup.
  • The final specialty blade, the Design E blade, is used for cutting or shredding solids suspended in liquid materials. Rubber and waxes are examples of solids that may be broken down using the knife edge design of the E Blade.

All of our dispersion blades are provided in 304 stainless steel and are made in the U.S.A. Many blades can ship on the day of order with only a short lead time for others. Available value-added features include tungsten-carbide coating and mounting hubs attached to the blade via welding or bolting.
