SAG Mill

01 06 2005  I work at a copper mine that has a SAG mill with 5 balls When we go in the mill for liner inspections you can feel balls exploding underneath your feet Last year my boss got cut in the ear by one I always thought that the balls exploded due to the internal stress generated by the outside cooling and shrinking faster than the inside.

MEI s Barry Wills The impact of milling costs on total mine operating costs

06 01 2014  It has been shown for example that the replacement of a SAG mill with a HPGR in a conventional SAG ball circuit may reduce grinding energy consumption by 15–20 Taking into account additional savings such as media and liner wear it was found that a grinding cost saving of 25–35 was potentially achievable with the use of HPGRs in such conventional circuits.

Gold extraction

Of the numerous major gold mining operations around the world most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present resulting in high mill feed rates.
