Can You Predict Powder Flow Behavior By Measuring Density
whether the powder will flow in gravity discharge from a storage vessel. Once a powder is compacted, the question is how much friction or resistance must be overcome for the powder particles to slide or flow against each other. The density test can only tell us how much compaction has taken place
