Modelling and optimization of the power draw of large SAG/AG mills is important due to the large power draw which modern mills require (510 MW). The cost of grinding is the single biggest cost within the entire process of mineral extraction. Traditionally, modelling of the mill power draw has been done using empirical models. Although these models are reliable, they cannot model mills and ...
