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 predried. A slightly more equivocal commitment to these mills occurred at Ellesmere Port in 1912. The ...
