The ease with which air can flow through a powder bed reflects the strength of particle-particle interactions, and specifically highlights cohesive interparticle forces. Because air accounts for a large volume fraction of any bulk solid, specific characterization of powder-air interactions can lead to improved understanding of packing behavior in bulk solids and flow of bulk particles in process.
Powder-air interactions will directly influence: drying, coating, pneumatic conveying, fluidized beds, dry powder inhalers, and more. Because powder-air interactions are strongly correlated with powder cohesion and cohesive behavior, this is also an effective tool to generally understand powder rheology phenomena such as flow, shear, and consolidation.
In this webinar you will learn:
· How to use direct measurements of air-particle interactions to better understand powder flow and packing behavior
· How to use measurements of air drag on powder particles to highlight interparticle forces separately from other contributors to powder flow
