Measuring filling is also necessary to estimate the composition of the load for mill modelling: rock and slurry for AG mills; rock, balls and slurry for SAG mills; or balls and slurry for ball mills. In the case of SAG mills, this requires two separate filling measurements: one for a crashstop and one following a complete grindout to quantify ...
