The output of the grinding apparatus is a comminuted mixture of ground granulated blast furnace slag (GGBFS) and ground limestone. Grinding the limestone with the GBFS does not require additional energy or substantially more processing time to grind the final product to a fineness suitable for use as a cement (typically <5000 Blaine (cm 2 /g)).
