The Filament Extension Atomization Process for Powder Production of Elastic Fluids

ABSTRACT The filament extension atomization is a promising process for spraying various materials with the potential to produce narrow droplet size distributions. This study systematically investigates the behavior of different fluids and suspensions in the process in order to determine its application limits and identify optimal process parameters. Particular attention was paid to the rheological properties, droplet size distributions, and circularity of the particles produced. The results show that the rotational speed of the rollers and the fluid loading are significant influencing parameters for the resulting particle properties.
