Characteristics of steel slags and their use in cement and ...

Use of LF slag for cement clinker production. Vilaplana et al. (2015) prepared a special type of cement containing high alite content at a laboratory scale, where ∼39% LF slag, ∼45% limestone, ∼14% shale, ∼1% mill sludge and 5% gypsum were used for cement manufacturing. The produced cement could be classified as the 42.5R Portland ...

butions of a HPGR finish grinding product and a ball mill + HPGR prod-uct are shown. This cement type con-tains clinker, limestone and trass and is ground to a fineness level of more than 5000 Blaine. These PSD analy-ses prove that it is possible to grind even very fine composite cement types in a highly efficient way if the system runs smoothly.
