    Table 1 lists a number of relatively high speed rod milling installations. No negative effects on the drive train liner life or the tendency for rods to tangle have been reported. A reduced lifting angle of the new liner leading face (e.g. 45 versus 90 degrees from the mill perimeter) is recommended for higher speed rod mills (Leclerq 1990)."

  • rod mill for gold miningeditions-masoin

    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.

    The first step in slag processing is size reduction to liberate metallic iron and iron-bearing minerals. This is done by crushers or by autogenous grinding that is the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80 Fe (Shen and Forssberg 2003).
