Abstract

PURPOSE:To make molten slag fine grains applicable to aggregate and at the same time, to effectively recover heat from the slag by dropping the molten slag onto horizontally rotating disks in succession so as to scatter and pulverize it by means of centrifugal force and supplying cooled air from the lower side.
