High Frequency Screens Versus Hydrocyclones For Closed ...

However, since high frequency screening is a relatively new development, the decision to use screens generally must be based on full scale screening tests of a slurry material of interest. In this paper the authors employ mathematical simulation models as an aid to evaluating the use of screens versus hydrocyclones for closed circuit fine grinding.
