The process of granulation in blast furnace slag (BFS) by gas quenching can effectively recover the waste heat of BFS and improve the valueadded nature of the BFS byproduct. With decreasing temperature, BFS crystallizes into melilite, anorthite, spinel, etc .
Blast furnace slag granulation plant technology. Blast furnace slag granulation plant technology, process, the applied granulation technology and operating conditions, storage and dewatering time, etc, and Figure 1, but this design results in minor amounts of slag carryover into the recycling stream, which could cause erosion of the recycling water, cooling tower plant and piping .
Slag Granulation Danieli Corus. Slag Granulation Granulation of Blast Furnace slag is a very attractive option since it turns the Blast Furnace slag into a valuable by–product that can be sold to the cement industry Blast Furnaces normally generate 200 to 400 kg of liquid slag. Sales Online
The molten blast furnace slag (BF slag) is discharged at the temperature of about °C, which contains a large amount of heat. At present, water quenching is the main technology to treat the BF slag, but this method not only consumes a huge amount of water, but also fails to recover the waste heat. Compared with water quenching, the dry centrifugal granulation has obvious advantages.
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

The envisaged annual capacity of the plant is granulation of 530,000 tons of liquid slag. The plant for granulation of blast furnace slag is an addition made within the scope of the modernization project for the existing Blast Furnace, and is also part of the technological entity for production of crude iron.
that no slag, matte, or alloy responds in similar fashion to a granulation practice. This paper addresses three issues, namely: • Watergranulation of BOF steel slag, without processing it to render it environmentally safe, physically and chemically acceptable for use by the construction industry, and the process economical

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 coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
