blast furnace slag granulation Slag handling is an important aspect of modern blast furnace operation. Today, blast furnace slag is a saleable product (granulated slag sand used as CO 2 -friendly substitute of clinker in cement production) rather than a difficult and costly waste material.
The 0.69Mt/yr ground granulated blast furnace slag (GGBFS) plant had an investment of US$31m, according to the Jakarta Post newspaper. Construction at the site started in 2014. Both the companies running the venture are state owned and they own an equal share each in the plant.
Characterization of Lead Blast Furnace Slag. Initial characterization of the lead blast furnace slag received from Herculaneum was through a) wet chemical analysis b) scanning electron microscopy and c) particle size analysis. ... We have all the laboratory and plant equipment you need to test or build/operate your plant.
Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape. Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than 3500 cm 2 /g.
Two types of blast furnace slag such air-cooled slag and granulated slag are being generated from the steel plants. In India around 40% of this slag is produced in the form of granulated slag. The specific gravity of the slag is approximately 2.90 with its bulk density varying in the range of 1200–1300 kg/m 3 .
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 ...
tests showed that plant growth was more active when the blast furnace slag aggregate was used. Furthermore, the use of latex was also found to promote vegetation growth, which is attributed to the latex forming a ﬁlm coating that suppresses leaching of toxic components from the cement.

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel.
The successful establishment of iron blast-furnace plants at Newcastle and Lithgow naturally invites attention to the economic utilization of the various products and by-products arising out of the industry.
" Blast furnace slag was included among the products that could be used in cement and concrete ... and recommended for procurement practices in order to …
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.
A modern blast furnace can produce more than a million tons per annum of slag. Slag granulation using water sprays is now an established technology that not only simplifies blast furnace casting floor operations but also provides an economical route for producing of a valuable raw material for a host of industries.
CHAENG (Great Wall Machinery) can undertake 20 tons --1.5 million tons of Blast furnace slag/Steel slag/Nickel slag/Manganese slag powder production EPC projects. Up to now, CHAENG has constructed more than 100 slag grinding production lines at home and abroad.
Blast furnace iron making is an example in which both unit processes that is reduction of iron oxide and smelting to separate liquid pig iron from slag is done simultaneously in a single reactor.
Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
Ground granulated blast-furnace slag (GGBFS), sometimes simply referred to as "slag", is a glassy granular material formed when molten blast-furnace slag is rapidly chilled, as by immersion in water.
such as Fly Ash (FA) from coal power plants and Granulated Blast Furnace Slag (GBFS) from the iron and steel sector. These materials are currently used as cement or concrete additions in the UK, thereby reducing CO2 emissions of the cement and concrete sector.
Besides production of hot metal and sinter which is used for internal consumption only we also sell blast furnace slag products, i.e., slag aggregate in several granulometric sorts produced mainly for construction purposes and also granulated blast furnace slag for further processing in cement factories and glass factories.
Integrated steelmakers sell blast furnace slag - which is naturally cementitious in quality - into the cement industry. In addition, the slag from the BOS plant such as converter slag and ladle slag has useful properties once weathered to allow for expansion of the lime-bearing material.
