  • Oct 26, 2011 · In this study, a computer simulation of a suitable matrix notation of the Broadbent and Callcott grinding model was written. First, a chromite sample was ground in the laboratory type batch ball mill at different grinding times, with different particle size distributions and different capacities. Second, elements of the matrix for computer simulation were found and a "milling matrix" was
