road sand mechanism production of stainless steel slag and processes

Ground granulated blastfurnace slag Wikipedia

Production and compositionEdit. To cool and fragment the slag a granulation process can be applied in which molten slag is subjected to jet streams of water or air under pressure. Alternatively, in the pelletization process the liquid slag is partially cooled with water and subsequently projected into the air by a rotating drum.
