Indonesia: Krakatau Semen Indonesia (KSI), a joint venture between Krakatau Steel and Semen Indonesia, has launched a slag grinding plant in Cilegon, Banten. The /yr ground granulated blast furnace slag (GGBFS) plant had an investment of US31m, according to the Jakarta Post newspaper. Construction at the site started in 2014.
The company specializes in manufacturing tube mills, rotary kilns, vertical mills and large steel casting and can undertake the EPC projects of cement production lines, active lime production lines, blast furnace slag/ steel slag/ nickel slag grinding plants, and its products are sold to more than 50 countries and regions in Southeast Asia ...
Blast furnace slag materials are generally available from slag processors located near iron production centers. Cements containing ground granulated blast furnace slag are available from many producers of Portland cement or directly from ground granulated blast furnace slag cement manufacturers.
The molten blast furnace slag is quenched almost immediately to form a material generally smaller than a #4 sieve. The efficiency, which the molten blast furnace slag is rapidly chilled, as well as the chemical composition of the slag source, largely determines its cementitious properties for use in concrete.
Depending on the availability of the raw materials and marketspecific requirements, further extenders are added to the common grinding process such as granulated blastfurnace slag. Mainly consisting of lime, silica acid, aluminum oxide, and magnesium oxide, blastfurnace slag is normally processed in granulation plants nowadays.

Ground Granulated Blast Furnace Slag (GGBFS) is a cementitious material and can be substituted for cement on a 1:1 basis. In addition to the performance benefits and cost savings this material requires 75% less energy to produce than traditional grinding processes.
The grinding plant will be designed in a way that besides granulated blastfurnace slag with a fineness of about 4,500 cm²/g (acc. to Blaine) composite cements – with varying portions of granulated blastfurnace slag, fly ash and gypsum – can be ground in various finesses.
Slag is mainly used for the production of cement, either as a cement mixture, can also be made nonclinker cement. After fine grinding blast furnace slag can be used as the main raw material for the production of slag powder. It can replace silicon bath soil insulation packing and save cost.
Manufacturing Skyway Cement requires two basic processes, granulation and grinding. ... In the blast furnace at the steel works, slag is produced when the mineral components of th e metal refining process separate from and float on the molten iron. The iron is drawn off to be further refined into steel and the slag is drawn off to be granulated ...

The slag can also be used to create fibers used as an insulation material called slag wool. Basic slag. Basic slag is a coproduct of steelmaking, and is typically produced either through the blast furnace oxygen converter route or the electric arc furnace ladle furnace route.
In this study, wet grinding was adopted to promote the activity of GGBS and the dissolution of gypsum. Wet grinded granulated blastfurnace slag (WGS), wet grinded phosphogypsum (WGPG), and wet grinded desulphurization gypsum (WGDG) were obtained in lab respectively. WGGBSWGPG system and WGGBSWGDG system were designed.
