The work purpose – studying of regularities of distribution of the humidified granules of porous ammonium nitrate in working space of the vortex granulator and thermodynamic conditions of processing of granules in a vortex gas flow. We carried out analysis of the influence of the velocity components of the gas stream on a trajectory of its movement in the working space of the vortex granulator. Features of distribution of granules on device height are investigated. The analysis of results of measurement of temperature fields in the vortex granulator (single-phase and two-phase flow) is submitted. Received results of researches will allow to develop mechanisms to control the movement of granules in the working space of the vortex granulating equipment and kinetics of removal of moisture from them.
