Ball Mill - an overview ScienceDirect Topics
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball Charge and Grinding Efficiency - Grinding ...
2021-5-5 What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points.

Charge behaviour and power consumption in ball
2001-8-1 Fig. 1 shows typical charge shapes predicted for our ‘standard’ 5 m ball mill and charge (described above) filled to 40% (by volume) for four rotation rates that span the typical range of operational speeds. For such a charge with a realistic size range, the free surface of the charge is well defined at low and intermediate rotation rates. For N=60%, material moves with the mill rotation ...

For chromite, the mill % solids did not appear to have any effect at low ball fillings, but a slight shift was observed at the higher ball fillings tested. The trend suggests that the size reduction of both silicates and chromite increased with an increase in ball filling, albeit at different rates.

But the rock also swells the charge, moving the center of the entire mass closer to the center of the mill, and thus decreasing the horizontal distance (d). The product of the new (larger) W times the new (smaller) d with the feed on is normally lower for mills operating with typical ball load levels. So the power falls when the feed comes on.
