Dry Grinding VS Wet Grinding Mineral Processing &

Dry Grinding VS Wet Grinding. A slight difference of condition between the two cases, however, is that with dry milling the fluid (air) fills the whole of the mill shell not occupied by the balls, whereas with wet milling the liquid occupies only a part of the mill volume not occupied by the solid charge.
