    Measuring Powder Flowability

    I am working on a project to measure the flowability of a ceramic powder through a pressurized pipe. After some initial research I am seeing several different methods of quantifying and measuring flowability. I have seen Hall flowmeters, Rheometers, Tumblers (Aero Flowmeter), and many different shear cells tests. Which one of these methods sounds most appropriate for what I'm doing?

    Also, does anyone recommend some available literature to read more about powder flowability?

    Thanks Jason

  2. I think the subject you are investigating is pneumatic conveying - most likely in the dense phase.

    Contact the following
    1 - Jenike & Johanson (USA)
    2 - TUNRA Bulk Solids Research (Australia)

    Professor R.D. Marcus (South Africa) has done a lot of work on this - see Marcus, Wiggill, Rizk - Parameters influencing long-distance pneumatic conveying systems - the Best of Bulk Solids Handling 1981 - 1985 Trans Tech Publications

  3. Powder Behaviour

    Contact Ajax Equipment at tech@ajax.co.uk for some information about the nature and behaviour of bulk materials.

  4. read my doctoral thesis

    Jason, if you contact me, I'll send you an electronic copy of my doctoral thesis, but also read my recent post. I have a ton of research papers and information on assessing powder flowability. Contact me, and we'll chat. James Cain, Brockport, NY USA.

    Watch This Video of Powder Flowability

    Jason,

    We've posted a video in our Youtube page showing the effortless flow of an alumina powder through our airslide equipment. Email me and I'll be happy to assist you with your concern. For further study about dense phase pneumatic conveying systems, you may visit us at http://www.pneuvay.com.au/feature/de...tic-conveying/.

    Kind Regards,

    Paul

    Dear Jason,
    for measuring powder flowability I recommend two methode which can be useful.
    We have good experiance with it.
    1. Ringschertest machine RST-XS of Dietmar Schulze
    2. Freeman FT-4 Powderrheometer

    Wich of the both method you will apply is depending on the application.

    Please contact us if you need more informations about characterising of powderflow properties.
    Regards,
    Daniel

    Physical properties of bulk solids

    We have over 20 years experience in powder flowability analysis.

    We are able to carry out all necessary measurements like yield loci, wall friction, density and/or moisture analysis on certified measurement equipments.

    We also offer the further calculations like statistical analysis, flow function, silo stress conditions reports, bridging and so on.

    For more information, please visit our website http://www.shear-test.com or contact me.

    Kind Regards,
    Markus
