The present study aims to develop a dynamical model of cement milling process as well as an autoregressive model of the errors of the previous one. Modeling is based exclusively on long term industrial data sets of five cement mills. Not only the dynamics of each mill is estimated but also separate dynamical parameters are computed for each cement type processed in the same mill.

Cement milling process pdf Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls).Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to

Read MoreBased on a dynamical model of the grinding process in closed circuit mills, efficient efforts have been made to optimize PID controllers of cement milling. The process simulation is combined with an autoregressive model of the errors between the actual process values and the computed ones. Long term industrial data have been used to determine the model parameters.
