This work describes a combined experimental-numerical study to characterizefine spray-dried powder used inthe ceramic tile pressing process. A DEM-based granular assembly is endowed with a new set of scaling laws thatallows for simulating reliably industrial processes using a much lower number of granules. To do it, a calibrationstrategy relying on three experimental setups is proposed; (i) compression test of bulk for granule stiffness, (ii)dynamic angle of repose and (iii) image analysis of the powder motion in a rotating drum for the intergranularand granular-boundary sliding and rolling friction coefficients. In order to evaluate the powder motion in a rotat-ing drum, a robust method relying on a direct image analysis is proposed. This methodology makes it possible toquantitatively assess the frictional properties of the powder in contact with different surface materials. [-]
