In terms of breakage mechanisms, while abrasion and impact prevail in ball mills, rod mills are used for their type of preferential grinding over larger particles . In general, in the milling stage, in order to avoid the generation of finer particles, the most desirable effect should be impact and compression, rather abrasion and shear, as ...

It was also revealed that the stirred mill and ball mill had varied effects on the minerals (Fig. 21). For all of the minerals, stirred milling was found to be producing more liberated particles than the ball milling and the difference between them became almost disappear through the fine grinding (from p 80 of 330 µm to 38 µm).
