Abstract Dry Granulation of Blast Furnace Slag for Heat

The disadvantage of wet systems is on the one hand, the recooling of the circulating water and on the other hand the need for drying of the granulated blast furnace slag, due to the residual moisture up to 20 mass percent. Furthermore the sensible heat of about 1.5 GJ/t of slag is lost.
