Abstract:
A process for granulating and comminuting molten material in which a slag melt is impinged by compressed water and is discharged together with at least a portion of vapour formed as a result of the compressed water impingement, comprising the steps of:forming a free flowing jet of slag melt in a container;directing compressed water jets against the jet of slag melt in a granulation space to produce a solidified and granulated slag;conducting the slag through a pneumatic conveyor duct and a distributor together with the portion of vapour formed during the production of the slag, said distributor dividing the slag and vapour into separate streams;transferring the separate streams into a grinding space via respective conically tapered nozzles joined to the distributor, said grinding space having a lower pressure than the granulation space; anddrawing off comminuted and solidified material from the grinding space.
