Abstract: A method for approximating the current mass distribution of granular material in the apparatus of fluidized bed dehydration with highly heterogeneous systems.

Keywords: mass distribution, approximation, the correlation coefficient.

Abstract: A mathematical model of a continuous process of granule formation of humic-mineral composites with desired properties in a fluidized bed using a model of fuzzy sets using MatLab environment.

Keywords: Fluidization, granule, fertilizer, kinetics.
