Control in Cement Production - ScienceDirect

01/01/1983· Cement grinding The control has the following goals: -to produce cement with desired fineness (specific surface and size distribution) -tc maximize the production rate minimizing the ener-gy cost . The grinding consumes a lot of electric energy, this is the highest percentage of the produc­tion cost. In many cases the use of lower cost off-peak energy is applied if possible. Most of the investedPROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL,The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large timeGrinding process and particle grading and water demand,,The separate grinding of cement is a grinding technology that saves electricity (reduced electricity consumption) and reduces carbon consumption (reduced carbon emissions). In addition, it optimizes the performance of the cement and meets the different requirements of the user for cement performance (such as the water demand of cement).
