Abstract
The article is devoted to the description of functioning conditions for the granulation module for the porous ammonium nitrate (PAN) production. We present general information on ammonium nitrate structure role in the process of ensuring the quality indicators of an industrial explosive. We substantiate the necessity of using PAN in the industrial explosives production. We introduce a method for obtaining PAN by humidification followed by thermal processing in apparatus with various configurations of fluidized bed and the use of active hydrodynamic modes. A technological scheme for implementing the method is described. We give a brief description of the hardware design of the granulation and final drying stage. The results of microscopic analysis of PAN granules are presented and the nanoporous structure features are described. The technique of technological calculation of the granulation device for the PAN production is proposed.
