The SAG mill rock charge properties (SMRC) and size distribution (smrc) are estimated by the reverseappliion of the SAG mill grate discharge function on the SAG mill discharge stream estimate, incorporating a size distribution assumption. Solids The mill rock charge mass by size, SMRC i, is calculated using Equation (8). i i i d c SMDC

Describing size distributions is easier when they are normalized into probability density functions, or PDFs. In this context, a PDF is a size distribution function normalized to unity over the domain of interest,, p(r) = C nn n(r) where the normalization constant C n is deﬁned such that Z 1 0 p(r)dr = 1 (7) In the following sections we usually work with PDFs because this normalization ...
