Design and Operation of Dry Slag Granulation Pilot Plant ...

2019-2-22  Some iron and steelmaking slag is granulated using water to produce granules suitable for cement replacement. However, this requires significant volumes of water and does not allow any heat to be recovered from the slag. Dry granulation could convert molten slag to SCM and also recover a large fraction of the heat in molten slag.

Some Fundamental Aspects of Dry Slag Granulation Process

2014-7-8  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 slag into a saleable product could result in significant reductions in waste and emissions associated with production of steel and cement. The present paper covers some of the fundamental aspects of the reactions taking place during dry granulation of molten slag. In particular, the cut in sulphur emission from slag during DSG as compared with conventional wet granulation
