摘要： Urea granules are prepared by spraying an aqueous urea solution having a urea concentration of 70-99.9% by weight on to fluidized urea nuclei in the form of droplets having a mean drop diameter of 20-120 .mu.m at a temperature at which the water is evaporated from the solution sprayed on to the nuclei and urea crystallizes on the nuclei to form granules having a desired size.

摘要： Stabilized NH.sub.4 NO.sub.3 containing granules are produced by dissolving in an aqueous NH.sub.4 NO.sub.3 solution Mg(NO.sub.3).sub.2 and, if desired, suspending mineral filler, spraying the resulting solution or suspension over nuclei maintained in spaced interrelationship and contacted with a hot stream of gas at a temperature of the nuclei of between 120.degree. and 135.degree. C., and cooling the resulting granules in such a manner that, between 70.degree. C. and 50.degree. C., they remain substantially homogeneous in temperature.
