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 ...

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...
