The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the chance of the material properties changing ...

Under dry conditions, only particles that directly filled the pots were observed, whereas under the wet conditions, particles mixed with water filled the pots. Accordingly, the wet grinding of the CNTs produced long fiber shapes. During the grinding process, the impact forces of the milling balls are different between the dry and wet conditions.

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.

Based on the media, two types of ball milling, namely dry and wet, are classified. As the name suggests, wet milling disperses the material in liquid media to form a slurry, while dry milling relies on particle contact. Although dry and wet milling can both be adapted for various materials, certain restrictions do apply.
