Structure characterization and grinding performance

2020-7-16  After the slag was heated to above 1500 °C and kept at a constant temperature for about 30 min, the molten slag reached a flowable state. When the liquid slag flowed out of the slag outlet and slag tank, the high-pressure nitrogen jet flowed through the nozzle to crush and granulate the liquid slag.

2020-4-8  On the way it passes a cross-belt analyser and magnet array to remove any remaining ferrous material. There’s a weighfeeder to regulate the mill feed. 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.
