Modeling breakage rates of coarse particles in ball mills
2009年6月1日 This has been demonstrated by Tavares and King (1998), who showed that fracture energies of particles coarser than about 0.5 mm were higher in the discharge when compared to the fresh feed of a ball mill grinding taconite. This is an indirect evidence of the lower breakage rates of tougher particles inside the mill, which survive the stressing ...
