(13h) Experimental Investigation of a Dry Slag Granulation

In this work, we have performed an experimental analysis on a dry slag granulation unit using rosin-paraffin wax mixture (liquid mixture in 4:1 ratio based on weight) as an analogue to BF slag. A spinning disc was employed to atomize the molten liquid mixture in the form of fine droplets under the action of centrifugal force.

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).
