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.

The clinker, along with additives viz. gypsum, slag, and/fly ash, called feed minerals, are introduced into the horizontally placed ball mill, which consists of steel balls of di erent sizes. The impact of these balls with feed materials causes grinding and they are lifted by a vertical elevator to the separator.

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
