Process for cooling hot ammoniumnitrate-containing granules, as well as granules obtained by applying this process. |
摘要 |
Hot NH4NO3-containing granules from a granulation zone, having a temperature above 90 DEG C are cooled in a first fluidbed to 55-75 DEG C, then aged without heating or cooling, and subsequently cooled in a second fluidbed to 30-50 DEG C. Preferably during the ageing step (1-10 minutes) the granules are treated with a coating agent. The granules obtained show hardly any tendency to cake together.
