An integrated steel plant generates a large amount of blast furnace flue dust – about 18–22 kg/t of hot metal – as a byproduct of the production process. The major component of this flue dust is iron oxides and coke fines. The recovery and reuse of this iron and coke is very important with increasing price of conventional resources.
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial byproduct of an iron blast furnace.
Cement Blast Furnace Slag. The coordinates of the grinding table diameter and number of rollers can be read off from the table. The xcoordinate indicates which product throughputs can be generated using the respective mills. The width of the fields is a measurement of the output factor.
