Cement Raw Material Mill

Modelling and simulation of raw material

The simulator calculates the chemical analyses and modules of raw meal in the mill outlet and also the dynamics of the main module characterizing raw meal and cement the lime saturation factor (LSF) Thus the effect of the raw materials compositions and their uncertainty on LSF dynamics is studied The dynamical models analyzed can be used to build robust controllers while the
