Blast furnace slag granulation at cast house

The process of slag granulation involves pouring the molten slag through a high pressure water spray in a granulation head, located in close proximity to the blast furnace Granulation process is the controlled quenching of the slag in cold water which does not give time for crystalline growth to take place Large volume of water is required (10 parts of water to 1 part of molten slag being .Pelletized blast furnace slag, in contrast to air-cooled and expanded blast furnace slag, has a relatively smooth texture and rounded shape Grinding reduces the particle size to a cement fineness for use as a hydraulic cement, which is typically less than cm 2 /g.
