2023 Artiukhova Granulation Unit for Modification and Obtaining of Ammonium Nitrate with Nanoporous Structure – Basics of Calculation and Design
Current paper is devoted to the description of the algorithm for obtaining porous ammonium nitrate granules in granulation units using devices with different configurations of the fluidized bed. We present brief theoretical background for calculation of the granulation plant main equipment. We propose the design of individual units for sequential implementation of the main stages of ammonium nitrate modification to obtain a nanostructured porous surface layer. We carry out an assessment of ammonium nitrate nanoporous structure quality and show further ways of improving the technology. Current work also pays attention to methods for ensuring the necessary specific quality indicators of porous ammonium nitrate by choosing the optimal technological unit operation mode and the design characteristics of the main equipment.
