Likewise, Hebbar (2011) has studied the grinding wear behaviour of austempered ductile iron as media material in the comminution of Kudremukh haematite iron ore in a ball mill. The grinding experiments were conducted under different pH conditions, pH = and pH =, while keeping other parameters fixed, at a mill speed of 74 rpm for 1 hr.

WhatsApp: +86 18838072829Most of the taconite used today requires very fine grinding. Prior to grinding, the ore is drycrushed in up to six stages, depending on the hardness of the ore. One or two stages of crushing may be performed at the mine prior to shipping the raw material to the processing facility.
