Abstract
An apparatus for converting molten elemental sulphur into solid pellets is described. Droplets of molten sulphur are passed through a liquid cooling medium, preferably water, the medium being maintained at a temperature range wherein annealing of the sulphur will occur. The pellets thereby obtained are hard surfaced, resistant to crushing and have low water retention in storage. In one embodiment semi-molten droplets are flattened during passage through the cooling medium by engaging deflection plates so that less flowable and more economically storable pellets are obtained.
