Rod Mill Design & Power Draw

For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2. Power draw is not significantly affected by the presence of the slurry in the mill. While the presence of the slurry will effect the charge density, the charge swelling ...

Ball Mill (Ball Mills Explained)

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
