Abstract

Cette invention se rapporte à des granulés poreux de nitrate d'ammonium qualité explosifs. Les granulés sont produits dans un lit fluidisé et sont formés à travers une combinaison de feuilletage et d'agglomération pour fabriquer des granulés de nitrate d'ammonium sphériques, lisses, durs, secs et qui ne se cassent pas facilement lors de la manipulation. Les granulés de nitrate d'ammonium d'une plage de dimension et d'une densité spécifiques peuvent être préparés; la plage de dimension ainsi que la densité de ces granulés peuvent varier en fonction de leur application, ce qui présente des avantages marqués dans la préparation de granulés destinés à être utilisés dans les compositions explosives ANFO.
