摘要
The construction of a complex model for the granulation of powdered materials in drum-type granulators is considered, taking into account structure anisotropy and layering on a surface. It is noted that granulation proceeds in several stages depending on the relaxation time of nucleation. The graphical interpretation of the layering of powder on the surface is given using the model. A rheological model for the consolidation of granules under the effect of external deforming stresses is presented that makes it possible to estimate the variation of porosity and density with the residence time. A comparison between calculated and experimental results is given.
