MPC in a cement plant, a model of the raw meal production process has to be established. This model includes many variables like frequency of sampling, time of analysis or retention time of raw meal within the mill. The great advantage of MPC against classic PID controllers is the ability of the MPC to anticipate future events and to

Raw Mill Feeding. In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Prehomogenization and raw milling, and has not been discussed separately by most of the authors. However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered.
