Would you like to carry out a powder rheology analysis?

What is powder rheology?

The rheology of powders is the study of the mechanical behavior and flow properties of powder-based materials. Unlike liquids or solids, powders consist of individual solid particles, and their behavior depends on several factors such as particle size, shape, density, and interactions between them (adhesion forces, friction, etc.).

Why carry out a powder rheology analysis?

Powder rheology is an essential analysis in many industries, such as the pharmaceutical industry, food, cosmetics, and chemicals, where powder materials must be handled, transported, or processed efficiently. It helps optimize processes such as mixing, storage, transport, and compression.

Which parameters are measured during a powder rheology analysis?

Écoulement en vrac : la capacité d'une poudre à s'écouler sous son propre poids, influencée par la cohésion entre les particules et l'humidité. Des poudres trop cohésives risquent de se bloquer dans des conduites ou des trémies.
Densité apparente et densité compacte : la densité apparente est la densité d'une poudre lorsqu'elle est simplement versée dans un récipient. La densité compacte est mesurée après compression. L'écart entre ces deux valeurs renseigne sur la compressibilité de la poudre.
Angle de repos : il correspond à l’angle maximal que peut former un tas de poudre avec l’horizontale avant que la poudre ne commence à s'écouler. Un angle faible indique une bonne aptitude à l'écoulement, tandis qu'un angle élevé suggère un comportement plus cohésif et difficile à manipuler.
Friction interne : la résistance à l'écoulement entre les particules elles-mêmes. C’est un paramètre clé pour comprendre le comportement d’une poudre lors de son transport ou son traitement.
