FIELD: chemical industry enterprises that product sulfur as final product. SUBSTANCE: sulfur is cooled and granulated when contacted with cooling agent such as water at 2-65 ^o C. Cooling agent is sprayed by means of nozzles and is directed towards drop stream of sulfur. Nozzles are disposed at angle of 10-90 ^o C. Range of heights is selected proceeding from complete crystallization of sulfur column of water curtain is formed, and dusting of sulfur is thus avoided. Amount of water being fed is batched and calculated according to formula.
