Sulphur granulation is a size enlargement process. Liquid sulphur is sprayed onto small sulphur seeds undersized granules and cooled to solidification. With repeated application of liquid sulphur, the seed increases in volume and weight. As the granule is enlarged, each coating of liquid sulphur is fully and structurally bonded to the layer beneath. This ensures a spherical granule, entirely dry and completely free of voids.



The process occurs in a rotating drum. Undersized granules, which serve as seeds, are fed into the granulating drum and lifted by flights attached to the inside of the rotating drum. The result is a continuous falling curtain of sulphur granules. Liquid sulphur is sprayed onto the seed curtain by a series of spray nozzles along the length of the drum. The cooling process is achieve by the evaporation of water, which is sprayed throughout the length of the drum from the process water system.
