Granulation machines with highly turbulized flows: creation of software complex for technological design

The article deals with author’s software products review to calculate devices with highly turbulized flows as a part of granulation units. Principal scheme and model of the granulation unit, algorithm of the granulation technical calculation are represented in the work. The complex automated calculation technique of the granulation units is proposed. The proprietary software for calculation of main stages in the granulation process is observed in the research. Short description and functions of main software products to implement basic algorithm are given: Vortex Flow©, Conical Channel©, Conical Granulator©, Multistage Heat Treatment©, Vortex Tray©. As a result of the optimization calculation, the user of programs will get the following information: optimal construction of the vortex granulator’s workspace, necessary number of stages in the multistage shelf drier for granules’ final drying, number and construction of the vortex tray with heat and mass transfer separation elements for exhaust gases cleaning. All software products enable to export the received data and to exchange these data between each other. The complex algorithm and software products, proposed in the article, let to carry out optimization calculation of the main technological equipment in the granulation unit at its designing stage without expensive multifactorial experiment. The presented granulation units’ calculation algorithm and software products for its realization enable to carry out equipment changeover if raw material characteristics and the productivity of the unit are changed. The automated calculations results give a base to design industrial granulation unit for porous ammonium nitrate production
