SAG Mill. SAG Milling breaks down ore through impact breakage, attrition breakage and abrasion. The primary design variables in SAG mills include the aspect ratio and the rotation speed. The rotation should be at a rate at which the ore material falls a maximum distance from the head to the impact toe (refer to Figure 3).

Processing - Citic Pacific Mining

Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.
