Method for measuring bulk density, tap density and the Hausner ratio for additives and feedstuffs

Following the purchase of a new powder compac-tion apparatus, Tecaliman decided to modify its measurement procedure for bulk and tap densi-ties, and the resulting Hausner ratio. The objective was to arrive at a procedure similar to the measu-ring technique used by Carr (1965), as applied to the Hosokawa apparatus. Abdullah and Geldart (1999) demonstrated that this technique did not give the same results as the method based solely on standard ISO 3953-1985, used previously at Tecaliman.
