An improved contact model for ball mill simulation by the …
The model is not implementation specific and requires only material parameters that may be obtained from standard tests. In addition, the model allows for a variation in the coefficient of restitution as a function of impact velocity. The implementation of this contact model is illustrated by simulating a 0.545 m diameter ball mill.

A direct approach of modeling batch grinding in ball mills …
Austin et al. (1984) proposed a more elaborate model where each individual design and operating parameter including mill diameter, rotational speed, ball size distribution, and powder filling were accounted for while computing the selection functions for the industrial mill. However, this method requires calculation of several empirical parameters.
