Abstract

Slag is granulated by making up a water/slag pulp & concn. of the slag in a vat with a conical bottom having an overflow pipe and a covering chimney. The bottom of the vat is connected to a siphon pipe debouching into a storage hopper at a lower level than the vat overflowpipe. The overflow pipe is pref. a circular channel separated from the vat by a grille and a series of water sprayers are disposed inside the chimney.
