Ball mills are different. The grinding media is unfixed steel ball, etc., which produces larger sized powder than grinding mill. the size of the discharged product can mainly be adjusted between 40250 mesh. If the size of discharged product is uneven, it is needed to equip a powder separating machine.

3. Differences on grinding medium between wet ball mill and dry ball mill. On the grinding medium, the dry ball mill only needs to join the steel ball, while the wet ball mill needs to add liquid to participate in grinding except for steel ball. The commonly used proportion: steel ball: material: water = 4:2:1.

Wet milling (also called wet grinding) is a process that requires a solid supply of energy with a lot of water added at each step. Wet grinding, therefore, is a costly process from a resources point of view. You can even find calculations that about ten calories of fossil fuel are burned for each calorie produced.

Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only. 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 times the drum diameter.

Surface roughness, particle agglomeration, and surface oxidation are higher in dry grinding than wet grinding, which all these effects on the flotation process. Moreover, dry ground samples in the pulp phase correlate with higher Eh and dissolved oxygen concentration. Therefore, dry grinding can alter the floatability of minerals.
