What is the difference between a SAG mill and ball mill?

A SAG mill is a semiautogenous mill that uses grinding balls like a ball mill. It is a primary or first stage grinder for grinding finer particles of ore. A ball mill is a machine for producing fine particle size reduction by friction and impact with steel balls. It is a common secondary or later stage grinder for grinding minerals.
