Researching of Powder flow behavior is an important issue in many new material industries. But the familiar method used does not meet the requirement actually. This article introduced the PFT (Powder Flow Tester) from Brookfield Engineering Laboratories Inc. It complies with the ASTM D 6128. The basic function includes the measurement and calculation of Flow Function, Wall Friction, Bulk Density, Time Consolidation Test with Flow Function, Arching Dimension, Rat-hole Dimension, Hopper Half Angle etc.
