The equipment which is widely used for the grinding purpose is semi-autogenous grinding (SAG) mill. SAG mills can grind huge amounts of input material, while being economically efficient and occupying lower physical space (Salazar et al., 2009). One of the most important characteristics of SAG mills is their throughput.
