    By contrast, attritionmillingrelies on a horizontal rotating vessel filled with a size-reduction solution. Treated to grinding media, the materials tend to be turned into free-flowing, spherical particles. This method, which includes theball mill, canreduce1,000 micron (20-mesh) particles of friable materials down to less than 1 micron.

    Ballhardness is in the 60–67 HRC range. They wear better than 440C stainless steel and through-hardened carbon steel. They are also recommended for applications where a through-hardened steelballis needed in larger sizes (½" and larger). They are sometimes packaged with a very light oil finishto reducerust due to humidity.

    Suppressing Heavy Metal Leaching through Ball Milling of

    Ball millingis investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) flyash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating flyashin a planetaryball mill, in which collisions between balls and flyashdrive various physical processes, as well as ...
