Process and apparatus for dry granulation of slag with reduced formation of slag wool

A process for producing substantially dry slag granules comprises adding a controlled amount of water to a molten stream of slag, and granulating the slag to produce solidified slag comprising substantially dry slag granules and slag wool. An apparatus for producing substantially dry slag granules comprises: (a) an inclined surface having an upper and lower ends for receiving and discharging the stream of slag; (b) a dispersion device at the lower end of the inclined surface for dispersion of the molten slag; (c) one or more water addition devices for adding a controlled amount of water to the molten slag; and (d) a collection area adjacent to the dispersion device for deposition of solidified slag produced by the dispersion. The quantity of slag wool produced by the process and apparatus is less than that which would be produced without the addition of water. 一种用于制备基本上干燥的炉渣粒料的过程包括：将受控量的水添加至炉渣的熔融料流；以及粒化炉渣以制备包括基本上干燥的炉渣粒料和炉渣绒的固化的炉渣。一种用于制备基本上干燥的炉渣粒料的设备包括：(a)倾斜表面，其具有用于接纳和排放炉渣的料流的上端和下端；(b)分散装置，其在倾斜表面的下端处以分散熔渣；(c)一
