Blast Furnace Slag Granulation Climate Technology Centre

Blast furnace slag is a nonmetallic byproduct of the manufacture of pig iron in a blast furnace. BFS consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. BFS forms when slagging agents (e.g., iron ore, coke ash, and limestone) are added to the iron ore to remove impurities.

Granulated Blast Furnace Slag an overview

Granulated Blast Furnace Slag An Overview

Today, blast furnace slag usage in the cement industry is known as slag cement. This term usually refers to either combinations of Portland cement and ground slag or to the ground slag alone. Within the current European cement standards, 14 listed cements may contain slag in different percentages by cement mass 8 .

Hatch Ironmaking Technologies Dry Slag Granulation

Hatch Ironmaking Technologies Dry Slag Granulation

Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.


Dry Slag Granulation With Heat Recovery

The current state-of-the-art practice is to granulate molten blast furnace slag in wet-granulation plants using large volumes of water. However, up until now it has not been possible to utilize the remnant heat energy of the molten slag, which amounts to approximately 1.8 GJ of energy per ton of slag.
