Abstract

Способ грануляции удобрения для введения мочевины непосредственно в матрицу шариков удобрения. Процесс включает введение мочевины в жидкой форме в матрицу и затем медленное охлаждение смеси материала шарика и мочевины для перекристаллизации мочевины внутри матрицы шарика. Результатом является значительно более твердая частица по сравнению с твердостью до обработки, пониженная растворимость при более длительном сохранении шариков и значительно меньшие проблемы, связанные с пылью и прочими проблемами обработки сформированных шариков.Отчет о международном поиске был опубликован 2000.01.27.
