Abstract: The stability of vertical mill raw meal grinding process affect the yield and quality of cement clinker. Due to the nonlinear of grinding process, random variation of working conditions, and large lag of the offline index test, it is difficult to establish an accurate mathematics model, thus cannot collect the optimizing operating parameters of vertical mill in time.

The operator of the mill has to stabilize the process during start up and to watch the stable running later on by comparing the actual process parameters with the wanted set points. The control loops are therefore in manual mode during start procedure (first 5 15 minutes after start) and switched to automatic after stabilization.
