An apparatus for manufacturing granules from slags produced in metallurgical furnaces such as blast furnaces, converter furnaces, electric furnaces, reverberatory furnaces comprising means for accelerating a stream of molten slag from a container to a velocity of at least two meters per second, and directing the stream onto a target surface from which it rebounds in the form of an inverted cone of droplets which are projected through the air to cool and to solidify them into granules.

Apparatus for producing granules from molten metallurgical slags

A method of manufacturing granules from slags produced in metallurgical furnaces such as blast furnaces, converter furnaces, electric furnaces and reverberatory furnaces. A molten slag stream from a container at a velocity of at least two meters per second is impinged upon a non-wetting target surface, from which the stream rebounds in a film of projected droplets having the shape of an inverted cone. Cooling and solidifying the droplets by their projected flight in air forms solid granules.
