Figure 3. Standard appearance functions for ball (Broadbent-Calcott) and stirred (Kelsall) mills (after Morrell et al., 1993.[1]

The Appearance function describes the mass-by-size distribution of progeny particles resulting from the breakage of parent particles.

The Appearance function may be specified for a particular ore.

Morrell et al. (1993) found the appearance functions generated for the Perfect Mixing ball mill model were too fine for stirred mills. They recommended either generating new appearance functions at one-tenth of the standard breakage test input energy level, or using the Kelsall breakage function.[1]
