摘要

Device for granulation of molten slags, especially blast furnace slags, comprising a slag channel, spraying nozzles and a closed chamber (3) of length at least 10 meter nozzles (4) are mounted directly under the slag channel (1) and consist of ultrasonic nozzles (sic), with a water pressure pipe (5) and an air pressure pipe (6) arranged so that a two-phase ultrasonic stream (14) from the nozzles impacts the slag stream (15) falling from slag channel (1) over its whole width.
