A mathematical model of heat exchange of the process of production of granular fertilizers in the fluidized bed
was developed. The mathematical models of the fluidization and granulation process in the fluidized bed are analyzed. The
main processes affecting the production of granular mineral fertilizers - heat exchange, mass transfer, vaporization,
crystallization - are determined. Transient characteristics of air temperature, temperature of granules and moisture content
of granules were obtained. The computer experiment confirmed the adequacy of the proposed mathematical model of the
process of production of granular mineral fertilizers in the fluidized bed. The main characteristics that affect the production
of pellets in a fluidized bed are air temperature and pellet temperature. To obtain a fertilizer of a given quality, it is
necessary to control the moisture content of the granules. The proposed mathematical model of heat transfer of the process
of production of granular fertilizers in the fluidized bed together with the controller can be used to build an automated
process control system.
