Item Research of the hydrodynamic and thermodynamic modes of vortex granulator’s operation for obtaining of porous ammonium nitrate(Lviv Polytechnic Publishing House, 2015) Artyukhov, Artem; Vedmedera, Volodymyr; Kremnyev, Oleksandr; Sumy State UniversityThe 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.Item Straitened movement of the granules in a vortex granulator(Lviv Polytechnic Publishing House, 2016) Artyukhov, Artem; Vedmedera, Volodymyr; Sumy State UniversityThe model of calculation of residence time of granule in vortex granulator in straitened movement mode is proposed. According the study of movement granules in changing its mass and interaction between each other conditions coefficient of conciseness for individual zones of vortex granulator is calculated.
