摘要：

A model of force balance is developed according to the analysis of forces acting on an agglomerate of cohesive particles in a fluidized bed. The parameters in the model are estimated. The sizes of agglomerates of cohesive powder are calculated with this model. The equilibrium agglomerate sizes calculated by this model are in reasonable agreement with the experimental values. Compared with the predicted values of existing models, the proposal model shows better results. (C) 1999 Elsevier Science S.A. All rights reserved.
