  • Patent number: 4218411
    Abstract: Molten sulfur is fed at a controlled flow rate into a spinning vessel located in an enclosure. Air is supplied to the enclosure by an evaporative cooler. A ring of sulfur ejecting nozzles each have an inlet communicating with the periphery of the vessel interior and an outlet communicating with the air in the enclosure. The molten sulfur is fed to the vessel at a rate lower than its discharge capacity. The sulfur is ejected from the nozzles at a temperature providing low viscosity directly into a cooling zone where its viscosity is rapidly increased and subsequently is atomized and cooled by fans on both sides of the ring of nozzles into which water is sprayed to form solid particles before appreciable agglomeration of the solid particle takes place. The solid particles are removed from the enclosure in a mixture with a substantial quantity of water saturated air, and then separated from the air by a centrifugal separator.
