PEGLOW, M.; KUMAR, J.  and  MORL, L.. Investigation of coalescence kinetics of microcristalline cellulose in fluidised bed spray agglomeration : experimental studies and modelling approach. Braz. J. Chem. Eng. [online]. 2005, vol.22, n.2, pp.165-172. ISSN 0104-6632.

In this paper a model for fluidized bed spray agglomeration is presented. To describe the processes of heat and mass transfer, a physical based model is derived. The model takes evaporation process from the wetted particles as well as the effects of transfer phenomena between suspension gas and bypass gas into account. The change of particle size distribution during agglomeration, modeled by population balances, is linked to the heat and mass transfer model. A new technique is derived to extract agglomeration and nucleation rates from experimental data. Comparisons of experiments and simulations are presented.

Keywords : Fluidized bed; Agglomeration; Drying.
