ABSTRACT:
A process for prilling molten materials, e.g. molten sulphur and molten fertilizer materials, in which molten droplets are prilled down a prilling tower into a countercurrent gas stream which carries drops of a volatilizable material which volatilizes on contact with the molten material and removes heat from the molten material so as to form solid skinned droplets. The solid-skinned droplets are collected, e.g. from a fluidized bed in the base of the prilling tower.
