In 1904, Krupp produced a self-containedcement millusing a ballmilland their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normalcement millinginstallation until 1920.
