Optimization Of Cement Manufacturing Process Sciencedirect

Aug 01 1987 Abstract. Cement manufacturing process is now operated with the aid of various control systems such as raw meal composition control kiln control and mill control. Those systems have greatly contributed to achieve uniformity of quality as well as cost reduction of cement. But from the viewpoint of optimization of cement manufacturing operation it is desirable to build an integrated control system which supervises and directs each control
