SLAG GRANULATION

摘要

A granulator for granulating molten material comprises a rotary atomiser to which the molten material is supplied. Without the assistance of fluid jets, the molten material is broken up into globules which are caused to pass through an air curtain containing entrained granules. This has the effect of accelerating the cooling rate of the globules to form granules and also of reducing the kinetic energy of the granules so that the length of their flight path is reduced thereby allowing the overall size of the granulator enclosure to be reduced.
