Abstract
The present invention relates to a method for granulating a stream of molten metal which falls from a launder or the like, down into a liquid cooling bath contained in a tank. The metal stream divides into droplets in the liquid cooling bath and the droplets solidify and form solid granules. The cooling liquid has substantially uniform flow across the tank in a direction that is substantially perpendicular to the falling metal stream. The flow of cooling liquid has a velocity of less than 0.1 m/sec. The distance from the outlets of the launder to the surface of the liquid cooling bath is kept less than 100 times the diameter of the metal stream measured as the metal stream leaves the launder.
