Closed circuit ball mill – Basics revisitedScienceDirect

01/04/2013· Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product). However, the individual effect of each, circulating load and classification,
