Slag recycling - recovery

The number of granulation plants for blast furnace slag has grown strongly. Since around 2000, the most important Chinese steel producers have been investing in granulation and grinding plants for blast furnace slag. It is currently estimated that 95 % of the blast furnace slag is granulated and used entirely in the cement and concrete industry.

Design and Operation of Dry Slag Granulation Pilot Plant ...

2019-2-22  The concept of dry granulation is that molten slag is atomized under centrifugal forces on a spinning disc, and the liquid droplets generated are rapidly quenched and solidified using air to produce solid slag granules suitable for use as a SCM, as per water granulation. The hot air can be recovered and used in other process operations.
