Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Prediction of 3D slurry flow within the grinding
Full three dimensional modelling of pilot scale SAG mills has also been performed over the last decade (see Cleary, 2004, Cleary, 2009a, Morrison and Cleary, 2008). It has also been used for modelling of axial flow in ball mills (Cleary, 2006, Cleary, 2009b). Prediction of slurry flow in a mill is a particularly difficult computational challenge.
