On the contrary, metallic objects such as steel nails or iron screws can damage the grinding tools which can lead to a considerable deterioration of the mill's performance. Therefore, it is necessary to separate the metal components before grinding ( with magnetic forces).

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.
