Abstract

Process for granulation of metallurgical waste and slags, more specifically for obtaining vitreous granulated materials from metallurgical waste and slags in the molten state by means of the use of water and means for projecting the liquid material into the air, characterized in that the mass of the waste, melted and distributed in the form of a curtain of liquid material, it is crossed by a transverse stream of water at high pressure but with a low flow rate, so that it projects a portion of the aforementioned material into the air, following a first, practically elongated trajectory, while the complementary to the untrimmed waste falls on an inclined plane, under a jet of water, to reach a rotating drum of fins that projects the waste particles into the air, following a second curved path, of concavity directed downwards, and that cuts the first one near the drum, after which the area of impact of the latter on an discharge area of the granules obtained.
