Yet, it remains unknown about the granulation characteristics of molten slag with different chemical compositions, especially at high throughput. In this work, we provided an experimental study on centrifugal granulation with four types of molten slags. The stage-specific centrifugal granulation was recorded and analyzed at first.

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

Centrifugal-granulation-assisted thermal energy recovery (CGATER) is one of the most promising routes to enable waste heat harvest from molten slags. However, it remains a grand scientific and technological challenge to produce fine particles from the bulk high-temperature molten slag, especially at large slag throughput.
