Abstract

При производстве упрочненных гранул из железосодержащих частиц железосодержащие частицы смешивают по меньшей мере с одним связующим веществом и водой или водным основанием с получением смеси, из смеси формуют гранулы и подвергают восстановлению с помощью подаваемого восстановителя. Для изготовления прочных гранул с одинаковым содержанием металлического железа смешивание выполняют так, что сначала железосодержащие частицы смешивают со связующим, а затем добавляют воду или водное основание.
