Abstract

Изобретение относится к способу применения флотационной машины, используемой в металлургических процессах, и к флотационной машине. Причем флотационная машина производит пеноотделение гидрофобных частиц от водного шлама, содержащего эти частицы. Флотационная машина содержит флотационную камеру (1) и ротор (2), который находится внутри флотационной камеры. Ротор (2) вращают с мощностью перемешивания, при которой в шламе поддерживается суспензия и воздух смешивается со шламом с образованием пены, и мощность смешивания регулируют путем регулирования скорости вращения ротора. Определяют количество твердых веществ S, накопленных на дне камеры (1), и скорость вращения ротора (2) регулируют на основе определенного количества твердых веществ. Флотационная машина содержит измерительное устройство (5) для определения количества твердых веществ, накопленных на дне камеры. Регулирующее устройство (4) выполнено с возможностью регулировки скорости вращения двигателя (3), который приводит во вращение ротор (2), на основе результата измерения измерительным устройством (5) с целью удаления твердых частиц со дна камеры.
