METHOD FOR GRANULATION OF RUBBER VULCANIZATION ACCELERATORS Russian patent published in 2003 - IPC

FIELD: methods for granulation of pasty materials by means of extrusion, in particular, granulation of rubber compound vulcanization, in particular, altax (di-2 benzthiazolyl)-disulfide), captax (2-merkaptobenzthiazolyl), diphenylguanidine, sulfenamids (brand "Ц"-N-cyclonexyl-2-benzthiazolylsulfenam, brand "M"-benzthazolyl-N-morpholylsulfide), applicable in the chemical, petrochemical and other branches of industry). SUBSTANCE: mineral oil is inserted in the pasty mass. Just before the extrusion the mass is mixed with recycle representing a finely divided product, so that the final moisture content of the paste would not exceed 40-55%. Then, extrusion of the pasty mass, formylation of granules and subsequent drying are accomplished. EFFECT: enhanced bulk density of the granulated product. 4 cl, 1 tbl
