Abstract

Procédé permettant de granuler et de fractionner des scories liquides, selon lequel des scories liquides sont introduites dans une chambre d'expansion et une zone de refroidissement. Les scories liquides sont aspirées dans une chambre d'expansion (4) se trouvant sous vide partiel et transportées dans la zone de refroidissement (10) à l'aide d'un jet de propulsion. Le vide partiel dans la chambre d'expansion (4) peut être réglé par l'intermédiaire d'une soupape d'étranglement (6) réglable située dans le passage d'introduction (3) des scories.
