DEM modeling of high shear wet granulation of a simple system

Publication date: May 2018Source: Asian Journal of Pharmaceutical Sciences, Volume 13, Issue 3Author(s): Saurabh Sarkar, Bodhisattwa ChaudhuriAbstractHigh shear wet granulation (HSWG) is one of the most poorly understood processes with known difficulties in optimization and scale up. The purpose of the current study is to develop a DEM model which can be applied under dynamic process conditions with high predictive capacity to improve process insight. The DEM model is used to predict agglomeration as a function of impeller speed and liquid addition rate in a high shear wet granulator. The DEM model tracks dynamic formation and breakage of liquid bridges between particles as liquid binder in the system is added, and corrects for the change in material properties as a function of the binder content.Graphical Abstract
