slag granulation plant. In slag granulation plant the molten slag is quenched and granulated: slag tapped per day 125 MT approx. slag flow rate 1.5 3.0 min; water flow 450 water pressure 3.0 kgthe invention relates to a liquid steel slag dry-process granulating device and a sensible heat recovery method. the liquid steel slag dry-process granulating device comprises a feeding device, a dry-process granulator, a cyclone separator and a sensible heat recovery device, wherein the dry-process granulator, the cyclone separator and the sensible heat recovery device are mutually communicated.some operations use slag additives to stabilize slag, but this solution is expensive and can limit the end use of slag due to inclusion of toxic elements. air granulation was hypothesized as a water-free method for stabilizing aod slag via rapid quenching.
