Flow characteristics of powder
WebJun 10, 2024 · 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. http://powdernotes.com/powder_notes/what-exactly-is-powder-flowability/
