  • Blast Furnace Slag Granulation / Ironmaking / Our

    Granulation, dewatering and storage of the slag can be done adjacent to the furnace or can be split up to suit available plant space or logistics. Modern condensation concepts and closed loop water circuits ensure effective environmental control.The INBA system with steam condensation is officially recognised as a Best Available Technology (BAT).

  • Design and Operation of Dry Slag Granulation Pilot Plant

    Feb 22, 2019· CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules. The hot granules are fed to a counter-current moving packed bed heat exchanger, where they are further cooled and finally discharged at close to ambient
