Feed Size, F80: Primary crushed ore is mandatory to feed any SAG mill. Typical feed size range is 80% passing 130 to 160 mm. Softer ores will be a little finer but the finer size is not sustainable when the ore becomes hard. Pre-crushing to finer sizes enhances throughput as does crushing of pebbles from the SAG mill (usually minus 60 mm).

Depending on the structure of the mill, the type of job that the mill is most suited to perform is determined. SAG mills have coarser feed sizes (sag mill feed) and process more material due to the bigger diameter and length to diameter ratios. Ball mills employ steel balls as the grinding media and are suitable for both wet and dry grinding.
