• Effect of Chemical Additives on Reduction in Mill Power

    Tumbling mills account major share of power consumption in mineral processing industries. In this paper, an attempt is made to minimize the power consumption in continuous grinding of chromite overburden by improving the grinding performance with different chemical additives. The additives taken are calcium chloride, sodium hexametaphosphate, sodium hydroxide and sodium silicate.

  • A charge mechanics approach to grinding mill power

    mills demands more operator attention than that of a few large mills. This results in a trade-off of costs between the choice of a number of small mills versus fewer large mills to grind the same total tonnage. Power consumption is also a major factor in mill design. Greatly increased power drafts are a natural result of larger mills.
