Limitations of Simple Powder Flow Measurements and Particle Size Analysis for Bulk Powder Characterisation


Limitations of Simple Powder Flow Measurements and Particle Size Analysis for Bulk Powder Characterisation
Freeman Technology is pleased to announce the release of a new application note “Limitations of Simple Powder Flow Measurements and Particle Size Analysis for Bulk Powder Characterisation”.
An important point to appreciate about powders is that they are essentially three-phase systems consisting of solid particles, liquid (often relatively poorly controlled levels of water) and gas, typically air. This is why particle characterisation alone cannot reliably differentiate samples when it is bulk powder behaviour – flowability, for example – that defines value and/or performance. It also highlights the limitations of relatively simple testing techniques which often have poorly defined methodologies and attempt to capture the complexities of powders with just a single number. For example, a promptly analysed sample may exhibit different flowability from an identic ....
