    We are currently investigating the pneumatic conveying of granulated matte (consisting mainly of Ni, Cu, Fe, S, Pt). This material has not been produced, so we are guessing the properties. If you have some experience on a system conveying a material of similar composition, please contact me.

    Regards

    As a pneumatic conveying system manufacturer, we have a pneumatic conveying database of thousands of different material tests. If we have a good description of the material (particle size, estimated distribution, bulk density, and material composition), we can search our database for a similar material. We then use this test data from the similar material to develop the conveying parameters for your application (rate, distance, degradation or wear limits, etc.). We can then apply a safety factor to the design depending upon your confidence in the material description you provided us.

    So, if you would like to entertain a proposal for a conveying system for your material, please feel free to contact me.

    PIAB is a world wide provider of vacuum conveying and has great experience in conveying products in the form of powders and granulates. We have a data base with evaluated tests on different kind of metal products like: Metal flakes, metal powders, metal granules and so on. PIAB vacuum conveyors are made of stainless steel to withstand virtually any corrosive material and if the substances are harmful, they can be reliably isolated from the surroundings. Two important thing for us to know is:
    1. Conveying distance and capacity. The sum of the horizontal as well as the vertical distances and the capacity in tons/hour.
    2. Material classification. To sum up, the following point should be included in the material classification:
    Fluidity/angle of repose
    Bulk density
    Abrasion factor
    Particle -size
    -distribution
    -form
    -density
    -hardness
    Moisture sensitivity
    Explosion hazard
    Harmfulness/poisonousness


    PIAB develops and markets vacuum products designed to simplify, speed up and improve the profitability of industrial processes. Our expertise is acknowledged in many countries, and our vacuum products are of the highest standard.

    Interesting question - we at The Wolfson Centre for Bulk Solids Handling Technology have conveyed hundreds of materials and have found that general information about material of a given "name" is often not relevant to another, nominally similar, product. For that reason, using information from a database is very dangerous as it can often lead to a misdesign. We usually undertake a conveying test with a sample of the material in question, and use the resulting data for design - that is safer. If you are interested in this approach, drop me an e-mail.
