The calcium looping CO 2 capture process, CaL, represents a promising option for the decarbonisation of cement plants, due to the intrinsic benefit of using the spent CO 2 sorbent as a feedstock for the plant. The generation of sufficiently active CaO from the raw meals entering the cement plant for the CO 2 capture requires calcination of these materials at around 900 °C in various ...

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.
