Figure 1: Dry Slag Granulation (DSG) Concept Dry slag granulation is based on molten slag atomization using a variable speed rotating cup or dish (see Fig. 1). The slag is fed from the slag runner via a vertical refractory lined pipe directly onto the center of the rotating cup.
Slag Granulation with Continuous Dewatering Ironmaking
Slag Granulation with the INBA Dewatering System Molten slag is often considered as a waste material when it is cast into slag pits. INBA slag granulation and dewatering system is the proven route for converting molten slag into a value added product for the cement industry. The INBA system comprises two main components
Effect of Water Granulation Conditions on Density and ...
Reducing the slag temperature to 1673 K or less is effective for adjusting the unit weight to 1.40 kg/l or more. Because the slag temperature is reduced to 1673 K or less in the new granulation system, the molten slag is granulated by blowing water after the slag is charged into the slag …
Some Fundamental Aspects of Dry Slag Granulation Process
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.
