Chapter 4: Bulk Powder Flow Characterisation Techniques

This chapter provides a review of the state of the art apparatus and procedures for the characterisation of powder flow properties. Classified according to the relevant state of consolidation, their measurement principles and the consequent procedure for different powder flow properties are described in detail. In addition, major available commercial devices are introduced, discussed and summarised based on the powder flow properties that can be measured. Finally, a comparison between the main features of different measurement methods with reference to the relevant powder consolidation, suitable usage, availability of standardised procedures and ease of self-construction of the rig is provided.
