Powder Flow Quality Bridging
quality of powder flow, jagged line analysis, number of peaks
Bridging, ratholing, arching and comparable behaviors are the bane of powder handling and formulating. The behavior is irregular and often catastrophic for achieving regular powder flow. Traditional powder testing methods cannot force the bridging to occur in a repeatable manner and thus they cannot discriminate flow differences between powders well. Stable Micro Systems’ Powder Flow Analyzer quantifies the bridging quality of powder flowability precisely and repeatably. Tight repeatability allows even subtle flowability differences to be quantified. This application study illustrates how a curve may be analyzed for the quality of powder flowability.
