### Wet vs Dry Grindingbulk-online Forums

2012/01/30 · It has been earlier shown that the effect of dry ball mill grinding increases considerably when the fines are efficiently removed from the mill. In this work autogenous grinding in small continuos scale has been undertaken to compare the effect of fine particle removal from the mill charge by efficient classification both wet and dry. In ball milling the desired particle size is achieved by controlling the time applied energy and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry
