Modeling breakage rates of coarse particles in ball mills ,jun 01, 2009 It is worth analyzing the mass balance equation for the case where the magnitude of the lowest impact energy in the mill is higher than the fracture energy of the toughest particle in the charge. this condition is approached by a mill that is fed with particles contained in a comparatively fine size range when compared to the ball size.Get Price
