Martin Earles first installed them for autonomous cement grinding in 1899 and in 1904 they were used exclusively at Norman for rawmilling coal and cement grinding As the mills ran cold for raw milling the material had to be completely pre dried A slightly equivocal commitment to these mills occurred at Ellesmere Port in 1912 TheCement is so fine that 1 pound of cement contains 150 billion grains The cement is now ready for transport to ready mix concrete companies to be used in a variety of construction projects Although the dry process is the most modern and popular way to manufacture cement some kilns in the United States use a wet process
