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 cementMost cement is currently ground in ball mills and also vertical roller mills which are more effective than ball millsGreater Detail: Cement Plant Operations Handbook Crewmen's Guide, Finish Mill Systems Cement mill A 10 MW cement mill, output 270 tonnes per hour A cement mill (or finish mill in North American usage[1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cementStage 4: Finish Process | Cement Production
