  • Slag granulation
    Patent number: 5409521
    Abstract: A granulator comprises a rotary atomiser (1) on to which the molten material to be granulated is poured in a stream. The rotation of the atomiser (1) causes the molten material to be ejected therefrom in the form of globules. No fluid jets are used to break up the molten material. The globules pass through an enclosure (6) and partially freeze to form granules which are collected in an annular trough (10). A gas is injected into the trough (10) to induce a circumferential movement of the granules within the trough towards at least one exit from the trough (10).
