Title
(EN) METHOD AND ARRANGEMENT FOR DETERMINING AN ESTIMATED BULK PARTICLE-SIZE DISTRIBUTION
(FR) PROCÉDÉ ET AGENCEMENT DE DÉTERMINATION DE DISTRIBUTION GRANULOMÉTRIQUE DE VOLUME ESTIMÉE
Abstract
(EN) A computer-implemented method is described for determining the bulk particle-size distribution, PSD, of granular material (2). The method comprises the steps of obtaining (101) a data representation of a surface of granular material (2) at a measurement point after at least one reloading of the granular material (2), determining (102) a measured surface PSD of the granular material (2) based on the data representation of the granular material (2), providing a computer model describing the relationship between the surface PSD and the bulk PSD, and determining (103), with the computer model and the measured surface PSD, an estimated bulk PSD.
(FR) L'invention concerne un procédé mis en œuvre par ordinateur pour déterminer la distribution granulométrique (PSD) de volume de matériau granulaire (2). Le procédé comprend les étapes suivantes : obtenir (101) une représentation de données d'une surface de matériau granulaire (2) au niveau d'un point de mesure après au moins un rechargement du matériau granulaire (2), déterminer (102) une PSD de surface mesurée du matériau granulaire (2) en fonction de la représentation de données du matériau granulaire (2), fournir un modèle informatique décrivant la relation entre la PSD de surface et la PSD de volume, et déterminer (103), avec le modèle informatique et la PSD de surface mesurée, une PSD de volume estimée.
