PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL

A 15 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance interms of system availability and output, however power consumption was on higher side 31 System Description Mill Rated capacity 150 t/h OPC at Mill Feed Sep Return Final Product System Fan Figure 1: Closed circuit grinding system milling system is a delicate task due to the multivariable character of the process, the elevated degree of load disturbances, the different cement types ground in the same mill, as well as the incomplete or missing information about some key process characOPTIMIZING THE CONTROL SYSTEM OF CEMENT In the grinding process heat will be generated and the cement will be heated up The temperature of the cement leaving the mill will be dependant on the temperature of the materials (especially the clinker) fed to the mill and to features of the mill and the grinding process It will typically be in the range from 90 to 120 deg CCement grinding Vertical roller mills versus ball mills
