Resumo

Throughout the years, the comminution team at the Federal University of Ouro Preto (UFOP) has been developing tools with the aim of making life easier for process engineers working in the area of size reduction. This work presents a software for estimating the parameters of the ore breakage function (Austin & Luckie, 1971) (Austin et al, 1984).
