Flow Properties of Powders and Bulk Solids
نویسنده
چکیده
In order to compare and optimize powders regarding flowability and to design powder handling equipment like silos, feeders, and flow promoting devices, it is necessary to know the mechanical properties – the so-called flow properties. In the present paper it is outlined which physical parameters describe the flow properties of a powder or a bulk solid, and how these parameters are determined experimentally.

Determining the geometry of mass-flow bins - some important considerations
It has taken some time to obtain general acceptance but in recent times, at least in Australia, competent designers of mass-flow bins use techniques based on the traditional concepts of Jenike to determine the appropriate geometry for mass-flow hoppers to handle bulk solids reliably. While the traditional Jenike design concepts may appear straightforward experience dictates that some important ...

In this study, the effect of some processing parameters on bulk density, particle density, particle size and some of powder reconstruction properties such as dispersibility, wetability and water solubility index of spray dried barberry (Berberis vulgaris) juice powders were investigated. A Pilot Spray Dryer (Two- Flow nozzle, counter- current, one cyclone) was employed for the spray drying pro...
