<p><P>PROBLEM TO BE SOLVED: To provide a water granulation method of blast furnace slag melting coal ash capable of suppressing fluctuation of water absorption by improving porosity and contributing also to recycling of resources. <P>SOLUTION: Provided is a water granulation method of blast furnace slag melting coal ash where granulated blast furnace slag is produced by jetting water to molten blast furnace slag 10 when molten blast furnace slag 10 melting coal ash is poured out from a slag ladle 11, wherein the molten blast furnace slag 10 of 30-100 tons stored in the slag ladle 11 is poured out from a pouring spout 12 which is formed at the upper part of slag ladle 11 and has a height of≥200 mm and a width of 50-1,000 mm. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
