Ance of infeasibility in optimization, handling of control degree of freedom, feedforward control for transient manipulation, and adaptation to the timevarying components in each raw material with kalman filtering estimator. it was applied to the actual control system of a cement process and a 72hour test.
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.
Cement Manufacturing Process | Phases | Flow Chart
Cement manufacturing process phase iv: kiln phase. kiln is a huge rotating furnace also called as the heart of cement making process. here, raw material is heated up to 1450 ⁰c. this temperature begins a chemical reaction so called decarbonation. in this reaction material (like limestone) releases the carbon dioxide.
Based on the studies of the manufacturing procedure of the cement industries, a selfoptimizing loadbased control strategy for the material pulverization system was proposed. both the hardware and the software implementations of the control system are illustrated in this.
By successfully monitoring the flow rate, the closed loop system was better able to control the feed rate into the finish mill which ultimately provided more efficient operation which created better (more valuable) final product. to conclude, it's about more than just check.
