The Effect of Grinding Media on Mineral Breakage Properties ... Hindawi

The Effect of Grinding Media on Mineral Breakage Properties ... Hindawi

The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...
