Analysis and validation of a run-of-mine ore grinding mill

Two types of mills commonly found in the minerals pro-cessing industry are ball and semi-autogenous (SAG) mills, which use both ore and steel balls as grinding media (Wei and Craig, 2009b). In the case of a ball mill the ore is crushed before it enters the mill, whereas a SAG mill re-ceives run-of-mine (ROM) ore directly (Stanley, 1987). A
