Dispersion Blade Myths

INDCO offers a line of dispersion blades with varying shear and pumping capacity.  The number, size, shape, bend of teeth and the tip speed will all have a bearing on the dispersion blade performance.  The finish of the blade, however, does not have an effect on blade performance.  Standard stainless steel blades have a 2B mill finish, smooth with a “brushed” appearance.  Mechanical polishing is impractical due to the forming method.  Electropolishing is available as an option by special request.  By the way, as you use your dispersion blade they tend to polish themselves due to the material hitting the blade.  Dispersion blades are used to create High-Shear in an application, which has a side effect of wearing the blade relatively quickly.

Another common myth is the assumption people make that since it is a “blade”, it needs to be sharp to work properly.  The truth is, a blade with a flat vertical leading edge works properly.  A blade that has had its leading edge “sharpened” to a taper over time becomes ineffective.  A new blade wears across the front of the teeth and eventually rounds off the corners.  If a person wants to get the blade back to its original performance, they must “dull” the blade with a file or grind the lead edge flat.
