circuit impact ball mill

Multiple stages may include a rod mill followed by a ball mill two stage circuit or a semiautogenous 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
