Powder Rheology 2: Methods for Powder Characterization and Anton Paar Powder Rheology
The second introductory webinar in the webinar series on powder rheology gives an overview of different methods for powder characterization - what they do, how they work, and for which applications they are useful.
Understanding a powder can be crucial for its processing, transport and storage. Knowing a powder's properties and behavior, like its flowability or cohesion, helps to run quality control but also to study powders in R&D or when up-scaling from R&D to high volumes. There is a large range of methods which enable the study of powders under different conditions and for different applications. It can be difficult to choose the right method as it depends on whether the samples are fluidized, deaerated, or consolidated, and how they are handled, processed, or stored. For example, to understand pneumatic conveying or a fluidized bed reactor, very different tests have to be run than if the caking in a silo is of interest.
Timothy Aschl is the global product manager for powder rheology at Anton Paar since 2017. He holds a PhD in chemistry from the École Polytechnique, France where he researched biosensors. His Master’s degree in technical physics was obtained from the Technical University of Graz, with a focus on biofuels.
