Abstract
MillPebs are grinding media ranging from 5 to 12 mm in size and produced by water granulation of molten steel. MillPebs were added to a 5.2-m-diam, 10.4-m-long grinding mill charged with 25-mm balls for processing iron oxide concentrate with a D80 of 0.6 mm. A six-month test demonstrated that the addition of MillPebs promoted the production of fine particles. However, a reduction in the quantity of 25-mm balls associated with the charging of MillPebs reduced the rate of breakage of coarse particles.
