  • PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL .

    Roller Mill (VRM) reduces the power consumption for cement grinding approximately 3040% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay characteristics also dynamics changes within 24 minutes. The fast dynamics necessitate closer attention to the process condition and taking corrective action ...

  • Predicting Particle Fineness in a Cement Mill

    processes, cement milling, is complex and nonlinear. There is a need to model the fineness of particles exiting the milling circuit in order to better control the cement plant. This paper explores the relationship between the particle size of cement produced and various sensor readings from the cement mill circuit. The aim of this pa per is to provide a model for predicting the fineness ...
