The article is devoted to the investigation of the structure of macro- and mesopores on the surface and inside of modified NH4NO3 granules. The main quality indicators of modified NH4NO3 granules are presented and the relationship between the nanoporous structure of granules and the quality indicators is shown. Various thermodynamic conditions for obtaining a nanoporous structure of the surface and...
The article deals with justification to choose optimal thermodynamic condiions to generate porous ammonium nitrate in the vortex granulators. Advantages of granules modification are justified by way of humidification and further thermal treatment. The necessity to improve technologies for porous ammonium nitrate generation is shown with aim to form meso- and macropores on the surface of the granule...
The first results are obtained, which confirm that the formation process of porous ammonium nitrate can be carried out in the drying agent's vortex flow with high intensity. It is proved that combination of humidification and thermal treatment methods of ammonium nitrate granules in the vortex weighted layer allows to get a product with developed nanoporous structure, high indexes of the absorptivity,...
The article represents vortex progressive equipment, which allows to generate nanoporous structure either on the surface of ammonium nitrate granules, or inside them. Therefore there is a possibility to get pores of various sizes in the inner, central and outer layers of granules. The engineering calculation algorithm of vortex granulator is investigated. The research results show that vortex devices...
