Abstract

Изобретение относится к флотационной машине и к способу улучшения эффекта флотации во флотационной машине, снабженной элементами (11) для подачи материала, подлежащего обработке во флотационной машине, элементами (12, 47) для удаления обработанного материала из флотационной машины, по меньшей мере, в верхней части флотационной машины и в нижней части флотационной машины, соответственно, смесительным механизмом (6), содержащим статор (8) и ротор (7), расположенные внутри машины, средством (9) для подачи воздуха в смесительный механизм и для образования слоя пены (14) в верхней части флотационной машины, по меньшей мере, одним элементом (13) для регулирования свободного пространства слоя пены, образуемого в флотационной машине. Согласно изобретению внутри флотационной машины установлен подающий элемент (15) для добавления текучего материала с целью разбавления суспензии в зону суспензии, по существу, над верхней частью ротора (7), но под зоной пены (14).Международная заявка была опубликована вместе с отчетом о международном поиске.
