#### Modelling SAG milling power and specific energy

SAG milling Power modelling Especiﬁc energy modelling SAG mills operation data abstract Comminution particularly milling is on average the largest consumer of energy in mining Actual com minution circuits consist in most of the cases in coarse crushing SAG milling pebble crushing and sec ondary ball milling . MODELING THE SPECIFIC GRINDING ENERGY AND BALL MILL 21 CONCLUSIONS Continued In the present work equations were also derived giving zthe ball mill power drawP as a function of its dimensions internal mill diameter D and length L zthe ball mill power drawP as a function of the feed D f mm and the product size d mm the Bond work index w i kWh/short ton and the mill throughput T short ton/h zthe ball mill dimensions D and L when . The Multiple Linear Regression EquationMay 31 2016· The multiple linear regression equation is as follows where is the predicted or expected value of the dependent variable X 1 through X p are p distinct independent or predictor variables b 0 is the value of Y when all of the independent variables X 1 through X p are equal to zero and b 1 through b p are the estimated regression coefficients Each regression coefficient represents the .
