Case study – Development of predictive methods and decision support tool of powders industrial behaviour
Sector : Agrofood
Client : Group
Our client faces frequent issues with powder handling (blocage en silo, mottage, durcissement, écoulement difficile,…) and wishes to improve its tools for the evaluation of candidates ingredients and for the development of its own products. RHEONISis here to develop predictive instrumental methods and integrate them into an decision support tool.
Industrial physical R&D for powders handling
RHEONIS hereby provides its expertises related to powders physics, industrial processes and phenomena and instrumental techniques.
In this large-spectrum study (almost 90 powders), the following tasks have been performed :
- Process analysis, information gathering regarding issues, recommendations for architecture of study
- Demonstration of the potentiel of physics behaviour powder rheometry techniques
- Systematic study of dry and wet behaviour for various parameters of phenomenological interest
- Ad hoc system development for moisture sorption and systematic study of hygrometry effects related powders
- Complementary measurement of standard parameters (granulometry, MEB, tapped-density, BET, angle of repose, floawability)
- Statistical analysis and conclusion on critical parameters and combined quantities of interest
- Cartography and decision-support tool development with excel macro
The need to overcome measurement standards in order to anticipate real-life industrial behaviour of powders
Our study confirmed that most of standard powders measurements are of almost null interest for discriminating or predicting industrial behaviour and issues regarding handling, processing or storing.
At the contrary, instrumental protocols based on powders rheometry shear-cell and fluidisation cell demonstrated the representativity of dynamical parameters with various effects. Hygrometry and thermal effects are strongly related with industrial issues, rendering moisture-sensitity or thermal-sensitivity measurement inevitable for issues anticipation.
Such a phenomenological approach and physics behaviours based R&D allows an efficient use of statistical methods for the extraction of the best correlations with industrial issues. Excel macros are then sufficient for implementing a basical but efficient decision-support tool.
