Slag sand is produced by first mixing a stream of molten slag with a quantity of between 0.5 m3 and 0.7 m3 of water per ton of slag to chill the slag while leaving it above the pyroplasticity threshold. Thereafter water at a rate of between 0.3 m3 and 0.4 m3 is added to the slag to stiffen the stream and this stiffened stream is fed to a drum rotating at a rate between 600 rpm and 1000 rpm to break it up into fine granules which are collected on a foraminous belt. |
