FIELD: chemistry. ^ SUBSTANCE: invention relates to a method of modifying and granulating sulphur and can be used in the industry of construction materials when producing binding materials. Method of modifying and granulating sulphur involves loading gaseous granulated sulphur and mineral filler into the hot mixer of a two-step mixer-granulator, mixing while heating to 135-150C, then loading pinene modifier, mixing to paste-like mass, moving said mass into the cooled mixer of said mixer-granulator, where granulation is carried out while cooling the granules, with the following ratio of components of the mixture, wt %: gaseous granulated sulphur 40-70, said modifier 0.05-1, mineral powder - the rest. The invention is developed in subclaims. ^ EFFECT: high fire safety, faster process for modifying and granulating sulphur. ^ 8 cl, 6 ex |
