Abstract

PURPOSE: To recover the heat of molten slag as well as make the slag granules for aggregate with high value added, by pouring the molten slag onto a rotary drum after which the formed droplets are cooled in a fluidized bed type cooler, passed through a classification tube to classify powder, and further cooled with gas in a moving bed type heat exchanger.
