An interesting case is the Saxon and Norman plants: the 1901 Saxon plant was installed with Schneider Kilns and ball-and-tube mills, while the "more modern" Norman (1904) had rotary kilns and Griffin mills. However, the Griffin mills were abandoned from 1912 and the Norman clinker was taken to Saxon for grinding.
