DRY SLAG GRANULATION WITH HEAT RECOVERY*

Dry Granulation Concept. Dry slag granulation is based on molten slag atomisation using a variable speed rotating cup or dish (see Figure 1). The slag is delivered on to the centre of the cup from a slag runner via a vertical refractory lined pipe. The rotation of the cup forces the slag outwards to the cup lip where it is atomised (see Figure 2).
