In this contribution a novel simulation tool, which is able to predict the agglomerate deformation and breakage during different loading conditions, was developed. This simulation system is based on the Discrete Element Method (DEM). For a better understanding of the soft, non-elastic deformation behaviour of wet and dry agglomerates, the models of liquid and solid bridges have been implemented in the DEM to perform a detailed simulation. As a result, the dependency of the restitution coefficient on the viscosity of the binder, impact velocity and agglomerate size and shape were obtained. © 2013 AIP Publishing LLC.
