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 cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Masonry cement continued its fiveyear downtrend, and output was estimated at less than half of that in 1984. Declines in Texas construction industries generally have caused a decrease in demand for portland cement. Texas Portland cement production was up 200,000 tons over that of 1988 but was still lower than the 1975 production.
