Abstract: Development of a Mechanistic Model for Fluid Bed ...
Partnering organizations realize that developing a detailed (CFD based) model for the whole granulation process is nowadays still a too ambitious goal. So the key strategy is to use information from such detailed models for development of more practical macroscopic models.

Discrete element modelling of a rock cone crusher 图文 百度文库
Over the past thirty years, DEM models have been widely used to investigate the mechanical behaviour of granular material. In recent years, the particle replacement method (PRM) has been widely used to model particle breakage using DEM. The PRM approach replaces the predicted failed parent particle by a number of new and smaller fragments.

The DEM model, with and without breakage, can define and/or represent the noted 17 attributes, with varying accuracy associated with cost and timing. Based on the DEM refinements, the PBM model selection function (S) can be refined to more accurately represent the ore breakage transformation and stochastic impediments.
