Dry Granulation of Blast Furnace Slag Steel360 News

Apr 04, 2019  Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Atomization is done using a rotary cup air blast atomizer (Fig 1). The particles cool as they travel through the air and are then cooled further in a fluidized bed. Both of these cooling processes provide ...
