Use measured flow functions, wall friction, and defined hopper geometry to check wall-angle suitability and cohesive arching separately, with a recalculated published example and practical decision worksheets.
Jenike shear cells and ring shear testers measure the same yield locus through different mechanics. Here is how their sample, stress range, and time differences map onto the mass-flow versus funnel-flow hopper design decision, plus a checklist for choosing between them.
Practical powder science for engineers, scientists, and process specialists.
Connect powder behavior to relevant measurements and better process decisions.
