Jan 01 2005 The SAG operator who has not been asked to ‘find a way’ to ‘push ore’ through the SAG mill is rare indeed! As a result many if not most operators view the SAG mill as a restriction in the grinding circuit that must be overcome instead of a comminution unit operation required to prepare ball-mill …

May 18 2020 SAG mills are still of major importance but I asked the question at Comminution ’12 whether ball mills would play a significant role in comminution circuits or would they be superseded by SAG mills. Chris Rule of Anglo Platinum felt that rod mills would play an insignificant role as they are severely limited in terms of size and ball mills may play a diminishing role as the upper feed ...

SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear - the sound of the mills standing still.
