Porous ammonium nitrate is a valuable agrotechnical fertilizer and one of the components of the common explosive ANFO, widely used in the mining industry [1].
The multistage process of moistening the granules of ordinary ammonium nitrate with various humidifiers and the subsequent heat treatment stages in vortex granulator is one of the most promising ways to obtain PAS (porous ammonium nitrate) as well as multilayer granules [2,3].
This paper presents the results of theoretical and practical studies to determine the dependence of the quantitative and qualitative characteristics of the porous structure of PAS granules on the intensity of wetting of ammonium nitrate granules in a vortex granulator.
The optimal moistening regimes for obtaining a developed nanoporous structure of ammonium nitrate granules are determined.
This work was carried out under the project «Small-scale energy-saving modules with the use of multifunctional devices with intensive hydrodynamics for the production, modification and encapsulation of granules», state registration No. 0119U100834.
