DEM investigation of SAG mill with spherical grinding ...

As the SAG mill enters a stable operation state, the grinding system's charging behavior in the PH-SP 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.

Grinding Mill - an overview | ScienceDirect Topics

If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, the SAG mill usually drives the discharge arrangement. This is because the SAG mill is usually of larger diameter and may have a requirement for screening of pebbles to protect the mill discharge pumps and cyclones, and to facilitate pebble crushing.
