Vertical mills tend to produce cement with a higher value of ‘n’. Values of ‘n’ normally lie between 0.8 and 1.2, dependent particularly on cement fineness. The position parameter is, of course, lower for more finely ground cements. 2.10.5 Characterisation of Separator Efficiency in a Ball Mill Circuit 18

A 10 MW cement mill, output 270 tonnes per hour. 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.
