Abstract: A method of granulating resorcinol/silica mixtures which comprises transporting a mixture of resorcinol and precipitated silica by conveyor worms to two pressing rollers whose shafts are attached vertically above one another and whose contact pressure can be varied, compacting said mixture between said rollers, breaking up the compacted mixture with a cake breaker to obtain a granulate with minimum grain size and separating the remaining dusty portion of said mixture. The mixtures can be added to vulcanizable rubber to provide improved adhesion to rubber reinforcements.
