wet grinding hydrocyclones

INCREASING THE CAPACITY OF THE GRINDING …

2007-7-26 · metals industry grinding circuits have been hydrocyclones (of various models and installation methods). Whether installed vertically or horizontally, no matter the configuration, generally the separation efficiency never surpasses 60%. The end result of these inefficient size separations is that most grinding circuits closed by hydrocyclones
