Abstract: Molten sulfur is fed at a controlled flow rate into a spinning vessel located in an enclosure. A ring of sulfur ejecting nozzles each have an inlet communicating with a conduit that extends tangentially from the periphery of the vessel interior and an outlet communicating with the air in the enclosure. As the sulfur is ejected from the nozzles, it is atomized. The atomized sulfur is further cooled to form solid particles before appreciable agglomeration takes place by fans on both sides of the ring of nozzles into which cooling water is ejected and evaporated. Each nozzle has a deflector at its outlet, and adjustable protrusions that interrupt the flow at the nozzle outlet to control the particle size. The solid particles are removed from the enclosure, thoroughly mixed with a substantial quantity of air, and then separated from the air by a cyclone centrifugal separator.
