Significant Size Reduction After Ball Milling

Oct 20, 2008 The size distribution produced by the ball milling of various crystalline and non crystalline materials, showed that initially there was a fairly even distribution over the size range up to 355μm. However, as milling proceeded two distribution modes developed one at about 90μm (the persistent mode) and one at about 250μm (the transitory mode).

    In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and or mill liner wear and.An important role in the efficiency of the crystallite size reduction during ball milling. As observed in the Table 1, the CR + BM sample has the largest crystallite size around 29 nm even after being submitted to both processes (cold rolling followed by ball milling). An acceptable explanation for this result is the occurrence of recrystallization.
