Get PriceMay 6, 2004 In this paper, a new approach for the calculation of the power draw of cement grinding ball mills is proposed. For this purpose, cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills, ranging in diameters from 3.2 to 4.8 m. The ball loads

Get PriceOct 7, 2014 minution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and sec- ondary ball milling. In these circuits the SAG mill is the largest energy consumer. In many engineering projects either a power equation and/or a specific energy equation are used for the designing of
Get PriceThe ore pretreatment flow charts in use at most high- productive processing plants designed in the last decade are based on semiautogenous (SAG) milling and involve as a rule primary wet autogenous mill (WAM) and a series of ball mills.
