Dry Slag Granulation: A Path to Improving the Safety and Hatch

Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of

Granulation This process transforms molten slag into granules. Skyway Cement receives granulated slag from a US steel manufacturer in Gary, Indiana. In the blast furnace at the steel works, The first step of the grinding process requires the slag to be dried down to about 2.5% moisture. These dried granules are then 

cfd simulation of free surface flow and heat transfer of liquid slag on

ABSTRACT. A novel process for dry granulation of molten slag using a spinning disc is being developed by CSIRO. Molten slag is atomised by a spinning disc under centrifugal force and slag droplets are quenched and solidified via air to produce glassy granules and recover waste heat. In the present work, steadystate 

Some Fundamental Aspects of Dry Slag Granulation Pyro

Abstract: There is a growing interest in development of a dry slag granulation (DSG) process so as to recover the sensible and latent heats from molten slags and convert iron blast furnace slags into a glassy phase that is a suitable replacement for Portland cement. The combination of waste heat recovery and conversion of

cementitious properties and produces granules similar to coarse sand. This „granulated‟ slag is then dried and ground to a fine powder. Although normally designated as "GGBS" in the UK, it can also be referred to as "GGBS" or "Slag cement" Concrete is basically a mix of fine aggregate, coarse aggregate and cement.

Blast Furnace Dry Slag Atomization and Recovery Sustainable

There are over 1,500 industrial blast furnaces worldwide, from which flows an estimated 1100 Mt/y of pig iron and 275Mt/y of slag. (Slag is the stony waste matter separated from metals during the smelting or refining of ore.) Blast furnace slag can be granulated then ground to produce a onetoone replacement for cement, 

Experimental study of rotating dry slag granulation unit: Operating

Aug 25, 2016 Blast furnace slag is a highvalue byproduct of the iron and steel industry. It leaves the plant at a very high temperature and possesses a large quantity of highgrade energy. One of the promising methods to extract this energy is dry slag granulation. In this study, the effectiveness of dry slag granulation was

Blast Furnace Slag Material Description User Guidelines for

These products include aircooled blast furnace slag (ACBFS), expanded or foamed slag, pelletized slag, and granulated blast furnace slag. . Although ACBFS can exhibit these high absorption values, ACBFS can be readily dried since little water actually enters the pores of the slag and most is held in the shallow pits on 

Ground granulated blastfurnace slag Wikipedia

Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Contents. [hide]. 1 Production and composition 2 Appliions 3 How GGBS cement is used 

China adopts Australian (CSIRO) dry slag granulation invention

Mar 15, 2015 Australian technology which harvests molten iron blast furnace slag and converts it into a granulated blast furnace slag make cement is being trialled in China where 60% of the world's iron blast furnace slag is produced. The process is considered environmentally within metal production, called Dry Slag
