The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.
The answer is the cyclones shouldn''t be used to try and control grind. The major factors that influence the grind-size are the feed PSD, ore characteristics (both the coarse breakage (Axb/DWi/WS AG etc), and fine grinding (BWi) parameters), grinding power, grinding media, classification efficiency and throughput rate.
