Документ Відкритий доступ Mathematical Modeling of Continuous Formation of Multilayer Humic-Mineral Solid Composites(2009) Kornienko, Yaroslav; Raida, Vasyl; Sachok, Roman; Tsepkalo, OleksiyA mathematical model of continuous granulation process of solid multilayer humic-mineral composites in the fluidized bed unit intended for liquid industrial wastes utilization with obtaining of complex granular fertilizers for environmentally safe agriculture was developed and the stabilization terms of the dispersion composition were defined.Документ Відкритий доступ Modeling of heat exchangement in fluidized bed with mechanical liquid distribution(Asian Research Publishing Network, 2019-06) Kornienko, Yaroslav; Liubeka, Andrii; Sachok, Roman; Korniyenko, BogdanThe uniform distribution of mineral and humic substances throughout the volume of granules in the preparation of organo-mineral fertilizers occurs in the layer-shaped mechanism of granulation. To achieve this goal, the introduction of a multicomponent heterogeneous liquid phase into a fluidized bed medium using a mechanical dispersant. The introduction of a liquid phase in the middle of a fluidized bed with the use of a mechanical disperser of conical type with a perforated surface can significantly increase the volume of the irrigation zone with the simultaneous movement of moist granules from the bowl of the dispersant outside, which eliminates the risk of formation of agglomerates and intensifies the renewal of the contact surface phases in the irrigation zone. The proposed mathematical model adequately describes the process of granulation with the use of a mechanical disperser located inside a layer of a granular material in the application of a pulsating mode of fluidization, which significantly intensifies the diffusion-controlled process in the presence of phase transitions.
