FIELD: chemistry.
SUBSTANCE: invention relates to the technology of granulating organic binding material, particularly bitumens, which are solid at normal conditions and can be used in chemical, petrochemical and other industries for making hot melt adhesive, as well as for making construction materials. The technical outcome is achieved due to that, the method of producing granular hot melt adhesive based on solid bitumen involves softening by heating the starting material at temperature ranging from room temperature to 50°C so as transform it into high-elastic state with subsequent granulation.
EFFECT: prevention of adhesion of granules without additional processing and reduced power consumption.
