As the SAG mill enters a stable operation state, the grinding system's charging behavior in the PHSP and SP grinding systems is different. As shown in Fig. 9, the shoulder and the head in the SAG mill containing polyhedral ore particles are slightly higher than that of the SAG mill containing only spherical particles. It means polyhedron ...

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.
