Slag cement is one of the most consistent cementitious materials used in concrete. It is actually a by product of iron production. It is often called ground granulated blast-furnace slag (GGBFS), When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.

Vertical grinding mill to make ground, granulated, blast furnace slag (GGBS) GGBS is granulated blast furnace slag, ground to very high fineness. When the molten slag from the blast furnace is tapped & subjected to a process of rapid cooling by jets of pressurized water, it forms granules, which is called granulated slag.
BOF Slag Granulation Plant. Steel slag from BOF (Basic Oxygen Furnace) steelmaking process was cooled by nature in the past. This material will swell and crack if directly used for road paving. Kingtech uses water quench process to release heat stress. The product size is ranged 2-3mm, steel granules and slag are separated. Granulated steel slag.
Although blast furnace slag contains a small component of elemental sulfur (1 to 2 percent), the leachate tends to be slightly alkaline and does not present a corrosion risk to steel in pilings (10) or to steel embedded in concrete made with blast furnace slag cement or aggregates.
The processing of BFS, starting from slag granulation, moisture reduction and finally grinding (comminution), leads to the production of ground granulated blast furnace slag (GGBS). GGBS can be added to cement or concrete mix as a partial replacement for cement, as stipulated by the national standards. The BFS obtained from steel plants ...

Typically BFS is then collected from the manufacturing source or blast furnace granulation bays and transported to the nominated processing facilities. The GBFS is de-watered and dried to reduce the moisture content before further processing (grinding) in a traditional cement clinker grinding plant, then ground to a fine powder.

Moisture in blast furnace slag, which occurs in the granulation process or in pelletized slag, should be removed by drying prior to the use of GGBFS as either an additive to Portland cement or a mineral admixture to Portland cement concrete. Grinding. Processing for use as a supplementary cementitious material requires grinding of the slag ...
Australia: Adbri subsidiary Cockburn Cement has approved a US$152m upgrade to its Kwinana grinding plant in Western Australia that includes a slag feed system. It says the investment will consolidate the cement operations at its Kwinana site. At present clinker is transported by truck from the Kwinana Bulk Terminal to cement mills at both the Kwinana …

Granulated Blast Furnace Slag. Granulated blast furnace slag is a glassy granular material that varies, depending on the chemical composition and method of production, from a coarse, popcornlike friable structure greater than 4.75 mm (No. 4 sieve) in diameter to dense, sand-size grains passing a 4.75 mm (No. 4) sieve.
Fly ash and Blast Furnace Slag for Cement Manufacturing. Granulated Blast Furnace Slag (GBFS) from primary steel making processes and Fly Ash (FA) from coal-fired power plants are currently used as additional cementitious materials. These are materials that can be added to clinker to produce cement or added to cement to produce concrete.
