DEM investigation of SAG mill with spherical grinding media …
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.
