Slag Resource Recovery Via Air Granulation
This air-driven slag granulation technology has been applied to the steel and non-ferrous sectors at full-scale, granulating up to 200,000 tonnes per year of slag per unit. Recently, we have demonstrated further scale-up of the technology to granulate high slag rates from blast furnaces and have implemented new adaptations of the technology to ...
Slag recycling
When the liquid (molten) slag is quenched with water in a granulation plant (Fig. 5), a glassy and granular product is created, which must subsequently be ground to produce a fine powder, which is used as a clinker substitute. Ground granulated blast furnace slag (GGBFS) has similar cement-like properties to Portland cement.
