Although the derivation of these curves is completely theoretical there is some qualitative evidence in support of their validity. Thus for example, it is clear from Fig. 8.2 that if a material is being ground by balls of approximately equal hardness (H= 1), then the ball wear may be reduced either by increasing or by decreasing the value of H.
