Abstract
Способ изготовления гранул мочевины в грануляторе с ожиженным слоем путем использования, по крайней мере, одного устройства для подачи материала, чтобы подавать расплав мочевины в форме пленки к ожиженному слою твердого ядра мочевины, на котором ядро растет путем отвердевания расплава мочевины на ядре, в котором количества биурета и воды в расплаве мочевины и в гранулах мочевины соответствуют такому соотношению:где b- % по массе биурета в расплаве мочевины; b- % по массе биурета в гранулах мочевины; W- % по массе воды в расплаве мочевины; W- % по массе воды в гранулах мочевины.
