A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
ball mill are now both operated in closed circuit with the new 2-Stage Koesep air classifier. It was a high priority to ensure that the old grinding system could still be used even during the ongoing modernisa-tion project. Finally a strategy was devel-oped that allowed the use of either grinding system. The old sepa-rator is still available
This paper presents the development of a non-linear model predictive controller (NMPC) applied to a closed grinding circuit system in the cement industry. A Markov chain model is used to characterize the cement grinding circuit by modeling the ball mill and the centrifugal dust separator. The probability matrices of the Markovian model are obtained through a combination of comminution ...
