Tubular Rod Mills. In Mineral Processing Design and Operations (Second Edition), 2016. Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of %. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.
