Barry Wills' Blog: A brief history of classification in grinding circuits

Aug 09, 2014  In our recent discussion, Prof. Alban Lynch expressed an opinion on the use of hydrocyclones in closed grinding circuits: "the way they are used now is an absolute nonsense, with circulating loads in some cases of well above 200%. The future is high frequency screens".This has led, unsurprisingly to a few comments on the use of hydrocyclones and screens in milling circuits.
