As there are no SAG mills and no ball mills in the HPGRHPGR circuit there are additional savings in CO 2 from the fact that steel ball consumption is zero. A further 15 megatonnes of CO 2 is therefore estimated to be potentially saved, giving a total saving of megatonnes of CO 2 or % compared to a AG/SAGBall mill circuits.

crushed ore is fed into a SAG/Ball mill circuit with a median size of approximately 12,000 microns. Most SAG Mills are operated in closed circuit with a screen. The screen fi lters undersized ore, normally minus ½ inch, to a ball mill discharge sump. The combined mill discharges are pumped to undergo classifi cation, normally via hydrocyclones.

8 years ago Like The volume of grinding media in a mill is directly related to grinding efficiency. The higher the volume of grinding media the more effective the grind. Balls must be added to maintain the media load and mill power draw. The power draw increases as balls are added and decreases as media wears down: add balls.
