  • Grinding Balls and Other Grinding Media: Key consumables
    Grinding Balls and Other Grinding Media: Key consumables

    Jan 25, 2021 The mills are partially filled with steel grinding balls or rods, commonly referred to as 'grinding media'. Mills need to be refilled continuously with new grinding balls as old ones wear out. Choice and consumption of grinding media is related primarily to the volume and charecteristics of the ore (abrasiveness, particle size, and specific
