Abstract

Procedimiento y dispositivo para la densificación de una mezcla de caucho vulcanizable, consistente en caucho y aditivos, con inclusión de un agente vulcanizador, en forma de un polvo escurrible teniendo un tamaño de partícula de 0,1 a 6 mm y una densidad de 0,4 a 0,8 g/cm3, caracterizándose el procedimiento porque se hace pasar la mezcla por una sección transversal continuamente decreciente a una temperatura de 0 a 60ºC, produciéndose una mezcla granular compacta aún no completamente homogénea que tiene una densidad de 1,1 a 1,4 g/cm3.
