mining technology: Iron Ore Processing for the Blast Furnace
A series of conveyor belts continuously feed the ore into ten large 27-foot-diameter, semi-autogenous primary grinding mills. Water is added at this point to transport it (94 percent of the water is recycled, while the rest is lost through evaporation). Each primary mill contains several 4" steel balls that grind the ore as the mills turn.

Mill (grinding)
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42'' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
