Представлены результаты исследований сгущаемости продуктов обогащения железосодержащей руды на лабораторной установке динамического сгущения собственного производства, моделирующей промышленный высокопроизводительный сгуститель. Определены параметры сгущения. Проведены опыты на питании с номинальной, пониженной и повышенной плотностями. Установлена зависимость содержания твердого в сливе от расхода флокулянта при различных нагрузках сгустителя. С использованием программного продукта FlowVision было проведено CFD моделирование гидродинамических потоков в теле сгустителя и подтверждены результаты натурных экспериментов.
