Ball Mill Explained - saVRee
Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit). 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.
