Fly ash and Blast Furnace Slag for Cement Manufacturing GBFS is slag from the iron production in Basic Oxygen Furnaces. When this slag is actively cooled and ground, GBFS is produced, which can be utilised as a cement or concrete addition. GBFS is said to increase durability of concrete due to an increased setting time, which reduces

The mill grinds the slag to around 4300 - 4500g/cm 3 (Blaine). To dry the slag while grinding, we need hot air, which is present in the mill at around 200°C. This is supplied by a burner from Loesche. The fuel is predominantly blast furnace gas, a byproduct from the blast furnaces that is high in carbon monoxide (CO).
