Mechanical Conveying-old Q&A

  •   We would like to develop a test method(s) or procedure to measure the handling characteristics of our dry bulk product in order to improve our bulk product. We have experienced bin and storage concerns and we would like to provide a measure to gauge improvements and product variation. Particle size measurement (PSD) is a bulk characteristic but not necessarily a direct indication of the dry fluid handling properties. What are the best property measurement methods to determine fluid handling characteristics?

    In addition to size distribution, there are other factors that influence flowability: bulk density, particle shape and friction, state of fluidization, compaction, etc. We have found that angle of repose is a basic gauge. Freeman Technology, Texture Technologies, and others take this several stages further and might be helpful as a resource.
