SAG Mills use a combo of ball milling and autogenous (letting the material crush itself) milling. They do have balls in them, but usually less of a load of them (820% load) than a ball mill (typically around 30% loaded). They also have plates on the inside that lift the load up and tumble it, like a dryer does.
