Blender Selection And Sizing For Powders

By Adam Covitt, Vice President, Federal Equipment Company

The goal of powder blending is a homogeneous, or uniform, consistent mix of materials.  The key to selecting a blender that will blend powders together into uniform mixes, also called "bulk solids," are the material's flow characteristics.  Free-flowing powders are more likely to blend well together, but not all powders are free-flowing.  Understanding the powder’s flow characteristics will help determine the best type of blender for the product.
