Abstract
Current paper is devoted to the study of formation process of a nanoporous structure in porous ammonium nitrate granules during their humidification and heat treatment in vortex devices. We briefly present the main methods for porous ammonium nitrate granules formation. We demonstrate that it is necessary to control the process of nanoporous structure formation by varying different technological parameters. We present a brief description of a method for producing porous ammonium nitrate granules with nanoporous structure in vortex granulators based on ordinary ammonium nitrate granules. The nanoporous structure of porous ammonium nitrate granules is investigated under various technological parameters of the modification process. We provide porous ammonium nitrate quality indicators and propose optimal parameters for its production.
