.Using automatic control for cement raw mill load can avoid appearing "empty mill" and "blocked mill" phenomenon, as well as save large amount of electricity. However, the grinding of the cement raw meal is too complex to establish mathematical model,which is nonlinear, big lag and difficult. Using some advanced or routine algorithm such as PID control algorithm can control the filling ...
