Wet milling of solids in ball mills is more intensive than dry milling. The reason for this has been explained by investigators [14] in different ways. Thus, the great effectiveness of wet milling is explained [1, 2] by the saturation of the unsaturated bonds of the surface of the material by water molecules.
