Many countries are considering alternative methods for increasing the output of fertilizers and fertilizer intermediates. Numerous studies have been made for various countries surveying alternative production schemes which could be utilized. The report gives details of granulation process based on the ammoniation of superphosphates with ammonia-urea solution in a rotary-type drum granulator. Granulation is a process whereby rounded or spherical particles are produced through a fusion, solution, crystallization, or cementing process between various materials. To obtain spherical particles, it is necessary to impart a rolling-type action to nuclei; these nuclei serve as a base for building larger particles which grow to product size. Information for this report is based on actual experience during startup and operation of a plant in Porto Alegre, Brazil. The ammoniation-granulation plant there consists of a volumetric-type solid feed system, ammonia-urea solution feed system, TVA drum ammoniator-granulator, dual pan granulators, dryer, cooler, and screening system. Data are given to illustrate the possibility of grades that can be made for a plant of this type.
