produced at 100 plants (102 including Puerto Rico) in the U.S. in 2010. Total cement production of U.S. cement plants in 2010 was about 66 Mt (excluding Puerto Rico); about 4% higher than the production in 2009 (64 Mt), which was the lowest since 1983 (USGS, 2012a). Clinker is produced with either the "wet" or "dry" process.
Read OnGreater efficiency, lower energy consump-tion, and maximum simplicity – these are the trends driving the development of grinding technology in the cement indus-try. Mills of various types are used in cement works, from grinding the raw material through to crushing the clinker into fine powder. Alongside vertical and
