ABSTRACT:
A method and apparatus for continuously generating sulphur seed nuclei inside the drum of a sulphur pelletizing system. The sulphur seed nuclei are generated in portions of the drum by elevating the temperature of the solid sulphur particles in the range of about 180.degree. to 230.degree. F. A portion of the sprayed liquid sulphur particles solidify into seed nuclei particles prior to contacting a falling curtain of solid sulphur particles in the area of the spray pattern having a minimum density of the liquid sulphur particles. The generation of seed nuclei may be confined to the feed end of the drum so as to leave the remaining portion of the drum available for product growth.
