01-01-1990· it is worth noting two things about these determinations of the breakage distribution functions; firstly, that they must be a satisfactory representation of the fracture behaviour in real equipment, and secondly, that even though at very high energy intensities the concept of single fracture must be no longer valid (because progeny fragments must

normalizable breakage such as in the traditional approach of Austin (1984). Models of comminution equipments require the determination of breakage distributions known as breakage or appearance functions for the characterization of the material breakage. For example ball mills can be modelled by the perfect mixing model given in Equation 1.
