SAG Semi-Autogenous Mill Steel Consumption

Does a SAG Mill reduce steel consumption? Do SAG mills cost less to operate compared to conventional rod or ball mill grinding circuits? Mining companies are always searching for new ways to cut costs. In order to be competitive and justify the tremendous capital costs of new projects, there has been a strong trend toward mills with a capacity of 36,300 or more tonnes per day (40,000 stpd
