Traditionally, Portland slag cement has been produced by inter-grinding cement clinker with granulated blast furnace slag in grinding mills (N. Patzelt, Finish grinding of slag, World Cem. Vol 10, 1993, 51-8). The traditional method and apparatus for using blast-furnace slag cement clinker production was patented in India in 1995 (2180/DEL/95).
