PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL ROLLER MILL (VRM) A REVIEW Vijaya Bhaskar B. and Jayalalitha S. Department of Electronics and Instrumentation Engineering, SASTRA University, India E-Mail: [email protected] ABSTRACT The power ingesting of a grinding process is 50-60% in the cement production power consumption.
The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of the process were ignored.
As each ball rolls through the counting chute, an electro-mechanical limit switch is activated, signalling the counter. Each count is added to the last, allowing a continual increasing total count of balls to enter the mill over a set time period. The total ball count can be monitored on the control panel at any time.
