Abstract
A continuous stream of blast furnace molten slag flows down through a trough. The slag stream is dispersed by blowing a jet air stream against the back side of the stream in an upwardly inclined direction crossing the stream. The dispersed slag is carried by the air stream to granulate the slag. The amount of the jet air stream is not less than 500 m.sup.3 per ton of the slag stream. The width of the jet air stream is greater than the width of the slag stream against which the air stream is blown. The speed of the jet air stream is 50-140 m/s at a nozzle outlet.
