the ball mill, but they can also be used as a one-stage grinder. the absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills. sag mills of over 40-foot diameter have been constructed. like the ball mill, the agsag mill will have a critical rotation speed above which grinding ceases. mill motor ball mills, expanding to 24, and then mills. In early 2010 abb commissioned the first gmds for two ball mills in chile with a rated power of 18.6 MW each. however, the toromocho project is pushing the limits further with two MW gmds being supplied to power two ball mills. abb will install an additional ft, MW sag mill and two ft, MW ball mills to the project in order to meet the challenge of higher-capacity production coupled with low ore grades. It obviously costs operators less in terms of capital expenditure to expand existing operations rather than build a new mine, and we have added more
