A dynamic mathematical model was developed for the simulation and control of cement rotary kilns. The model consists of a set of nonlinear partial differential equations, and represents the material and energy balances in the kiln. Based on some logical assumptions, the model does not only consider the reaction mechanisms but also reduces the complexity of computer simulation.
