    Comparison of DEM and experiment for a scale model SAG

    01/01/2003· The magnitude of change in power draw from a 65% mill to speed to 75% seems to be too small, but for the 95% mill speed, sharp drops are reported that are not consistent with the observed rising center of mass of the charge. This suggests that the base load has been under-estimated leading to a proportionally large over-estimation of the charge related power draw. The quoted experimental power

    Throughput optimisation in milling circuits

    SAG Mill Power. SAG milling can be optimised to achieve maximum breakage and throughput (or any other number of objectives). The relationships between the key variables are highly non-linear and shift as the ore hardness, steel load and liner conditions change. Traditional and basic control and modelling techniques are therefore not veryfective. A Model Predictive Control System such as
