Method and arrangement for determining an estimated bulk particle-size distribution

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 gran...

Zusammenfassung: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.
