- effect of rpm in grinding mill
The standard practice is a single autogenous mill or semi-autogenous mill followed by a pair of ball mills which grinds the run-of-mine ore to a size suitable for flotation. AG/SAG mills produce a product size that is suitable for finish grinding in a ball mill, stirred media mill or a vertical mill.
