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 steam explosions resulting from the inappropriate contact of slag with water.

Wet granulation of titania slag Description and operation of the wet granulation plant Wet granulation of titania slag was carried out at the research and development facilities of Exxaro in Pretoria. Ilmenite was smelted in the 1.5 MW DC furnace at this facility. The typical titania slag tap mass was approximately one ton.

Ground granulated blast-furnace slag - Wikipedia

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 is highly cementitious and high in CSH (calcium silicate hydrates) which is a strength enhancing ...

Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Atomization is done using a rotary cup air blast atomizer (Fig 1). The particles cool as they travel through the air and are then cooled further in a fluidized bed. Both of these cooling processes provide ...

MINERALOGICAL CHARACTERISTICS OF SLAG (FROM THE

The term granulation involves rapidly cooling the liquid-hot slag under the pressur-ized cold water and obtaining the slag in the form of irregular granules. The quality of granules depends on the chemical composi-tion of slag, slag temperature before spillage, rate of slag spillage, pressure and the amount of cooling water [4].
