Production of urea-ammonium sulfate

摘要: A process for the production of urea-ammonium sulfate granules from urea and ammonium by several granulation methods. The proportion in mixture was varied 15 percent to 70 weight resulting products containing 42 29 N 3 17 S, respectively. Unexpectedly, these proportions were fluid enough at 250* F. 325* be prilled granulated. presence increased strength significantly.
