PROCESS CONTROL FOR CEMENT GRINDING IN 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 time delay characteristics also dynamics changes within 2-4 minutes. The fast dynamics necessitate closer attention to the process condition and taking corrective action,OK™ mill The most reliable and efficient mill for raw and,,Mill (VRM) designs for raw, fuel and cement grinding for several decades. The OK™ mill has been FLSmidth’s standard cement VRM since 1993. Since its introduction, the OK mill has proven to be the most efficient cement VRM available, with the highest reliability and ease of operation. In 2017, FLSmidth introduced the OK raw mill, which is designed with the same proven technology and modular,PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL,• Vertical roller mill (VRM) • Ring roller mill or Horo mill Even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants. In this paper authors are covering the process diagnostic study of Ball mill for cement grinding. 2. METHODOLOGY FOR PROCESS DIAGNOSTIC STUDY : BALL MILL,
