Slag recycling - recovery

Granulated blast furnace slag is primarily used in Europe for the production of Portland blast furnace cement. The necessary grinding of the slag to the finenesses required for cement is now mostly performed in vertical mills (Fig. 7), which achieve throughputs of over 100 t/h.

Technical and Environmental Benefits for Dry Atomization

Air atomization is widely practiced in the steel industry for EAF and BOF slags. This paper describes the proposed mechanism for LMF and AOD dust formation and how dry slag granulation can overcome the issues associated with dumping and slow cooling. Benefits of dry slag atomization include the ability to directly stabilize the slag, enhance or
