Morrell C-model

Morrell C-model. Applies to both SAG and ball mills, with variants for grate-discharge and overflow mills. This model was developed as part of the PhD thesis of Stephen Morrell at the University of Queensland and is the model used in the JK SimMet software for determining mill power draw. It is described as the "C-model" and should not be ...

Modelling SAG milling power and specific energy

In his approach the total specific energy of the entire AG/SAG circuit is firstly predicted using the SAG mill feed F80 and the ball mill cyclone overflow P80. Morrell's model (Morrell, 2011) relates the feed, mill geometry and operating conditions to the specific energy of the circuit. However, the F80 is not enough to represent properly ...

Prediction Models for AKI

The ACT model's discriminatory ability for severe AKI suggests that sTNFR-1 levels, the presence of cirrhosis, and age may modify the risk of AKI. The high c-statistic, specificity, and NPV of the ACT model are impressive, but the clinical utility may be limited when the outcome is rare and the test has limited sensitivity and PPV.
