A model for batch rod milling ScienceDirect
A model for rod milling is proposed which states that the top sizes present in the distribution are broken preferentially. For the small mill used in the tests the enhancement of specific rate of breakage is about, that is, when a particle is in the top 15% by weight it breaks times as fast as when it is in the bottom 85% by weight.
