摘要

Preparation of ammoniumnitrate-containing granules by spraying an ammoniumnitrate melt or solution, containing 0,3-3,5% wt of calciumnitrate and 0,5-5% wt of a thermal stabilization agent, onto or into a bed of ammoniumnitrate seed particles, which are kept separate from each other and are contacted with a gas current, and which have a temperature of 95-145 DEG C. …The granules obtained are thermally stable and have a low water content and a high bulk density.
