Rod mills, how they function

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.

Mining in Minnesota

The taconite is crushed, processed into hard, marble-sized pellets, and shipped to steel mills. The taconite pellets are melted in blast furnaces and then blown with oxygen to make steel. Minnesota currently has seven operating taconite plants which make the pellets. About 44 million tons of taconite pellets were shipped from the state in 1996.
