Fullscale closedcircuit cement ball milling was modeled using a true unsteadystate simulator (TUSSIM), based on a transient cellbased population balance model (PBM) with a set of differential algebraic equations (DAEs). As a major novelty, the PBM for the mill was coupled with a dust loaddependent, variable Tromp curve for the air classifier.
