Abstract

Process and device for the densification of a vulcanizable rubber mixture, consisting of rubber and additives, including a vulcanizing agent, in the form of a squeezable powder having a particle size of 0.1 to 6 mm and a density of 0, 4 to 0.8 g/cm 3, the process being characterized in that the mixture is passed through a continuously decreasing cross section at a temperature of 0 to 60º c, producing a compact granular mixture not yet completely homogeneous having a density of 1.1 to 1.4 g/cm3.
