Dry Granulation of Blast Furnace Slag Steel360

04042019· 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 provideThis process results in the formation of sand size (or fritlike) fragments, usually with some friable clinkerlike material The physical structure and gradation of granulated slag depend on the chemical composition of the slag, its temperature at the time of water quenching, and the method of productionBlast furnace slag granulation | Climate Technology Centre
