  • Process and apparatus for making expanded slag
    Patent number: 4115089
    Abstract: Expanded slag, especially blast-furnace slag of Thomas melts is made by passing the slag along a trough in which water is fed into a layer of the molten slag. The slag is then permitted to cascade downwardly along an inclined surface which is wetted with water and finally is dispersed by a rotating disintegration drum and curtain of finely divided water. The expanded slag has a lower density, a more complete expansion characteristic and a greater uniformity than conventionally produced expanded slags.
