The ball milling process is generally divided into two types, the dry ball milling process, and the wet ball milling process. This article takes dry ball milling as an example to introduce the ball milling process. First, select the appropriate size and weight of the grinding medium according to the particle size of the grinding material.

How to choose dry and wet ball mill. 1. Correctly choose the feeding way of dry grinding and wet grinding. Whether feed the material dry or wet depends entirely on the subsequent operations in the ball mill and the nature of the produc Some materials require dry grinding because they will undergo physical or chemical changes after adding water.

The mill can be fed from one end with the product removed from the other end or, alternatively, the mill can be fed from both ends with the discharge at the centre. The process can be wet or dry but generally it is carried out wet. Maximum rod length is about 6 to 7 meters, otherwise there is a risk of the rods bowing.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Wet milling Wet milling with IKA's inline machines is a safe and efficient alternative to dry grinding. Dry grinding creates a lot of dust which causes the need for proper filtering systems. This can be of particular importance during grinding of substances whose dust, when mixed with aerial oxygen, can result in explosive mixtures.

Wet milling of solids n 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 u saturated bonds of the surface of the material by water molecules.

The terms wet milling and dry milling are overarching concepts that do little to actually describe the processes and forces involved. But some methods are only possible under wet conditions, and some require dry milling conditions. Although the goal of both grinding methods is to reduce particle sizes to a target range, the processes are different.

Chapman et al. (2013) compared the effects of using different circuits HPGR (dry) rod mill (wet) and cone crusher (dry) rod mill (wet) on the flotation of base metal sulfides. They indicated that apart from the grinding environment, HPGR could produce finer particles than a cone crusher. This difference was higher in the fully dry system.
