Cement mill Wikipedia
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.

PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The 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

Soft sensing of particle size in a grinding process
Cement fineness is an important quality parameter in the cement grinding process. However, very few studies have been done for soft sensing of cement fineness in the grinding process. Moreover, most of the grinding process modeling approaches have been reported for ball mills and rarely any modeling of vertical roller mill is available.
