  • My Hopper Design Cliff Notes provide a nice summary of flow property test methods and bin design.  When I give workshops, I provide these notes along with a spreadsheet that performs the calculations.
  • Caking and its Prevention is the non-copyright version of an article that I wrote for Chemical Engineering magazine.
  • Optimization of Pharmaceutical Formulations for Flow shows how Jenike's flowability coefficient FFC can be misinterpreted.  It's better to measure  the flow properties of a powder over a range of consolidation pressures so that critical hopper outlet dimensions and hopper angles can be calculated.
  • I periodically add other documents on powder handling and processing.  Be sure to visit and check for updates.
