Abstract: In order to analyze the effect of the blade installation height on the granulation performance of a dry granulator, a mathematical model based on the Eulerion-Eulerion concept was established. It used the finite volume method and simulated the particle volume distribution in dry granulation process. Results show that particles dispersion and granulation result were the best when the minimum distance between the blade and the granulation chamber was 15 mm.

Key words: blade; Eulerion-Eulerion model; numerical simulation; distribution
