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.

Abstract: A process for turning powdered rubber into industrial products, comprises mixing the powder with heat tolerant additives. The composition is then mixed intensely to provide mechanical heat, before being cooled and extruded. A process for turning powdered rubber into industrial products, comprises mixing the powder with heat tolerant additives. The rubber and certain additives are subjected to intense dispersive mixing so the particles warm mechanically and are in a plastified state. The viscous material is then cooled, and at the end of the cooling phase, heat sensitive additives and/or wetting chemicals are added. The mixture is then supplied to a mixing zone where it is further mixed. The material is worked in a twin worm extruder (1), which has a kneading element in a kneading section (5).
