Title (EN) PROCESS AND PLANT FOR PRODUCING TYRES
(FR) PROCÉDÉ ET ÉQUIPEMENT DE FABRICATION DE PNEUS
Abstract:
(EN) A compound plant (100) adapted for processing elastomeric compounds for tyres with both a high quality and a high throughput is disclosed. At least one batch mixing device (101) is put in combination with at least one multi-shaft continuous mixing device (106) having a high number of shafts. For example, the multi-shaft continuous mixing device could be a ring extruder having a plurality of co-rotating screws disposed to form a ring.In operation, a first elastomeric compound (104) is discharged from the at least one batch mixing device (101) and processed with the at least one multi-shaft continuous mixing device (106) to obtain a second elastomeric compound (108).
(FR) L'invention concerne un équipement (100) de traitement de composés conçu pour traiter les composés élastomères pour pneus avec à la fois une qualité élevée et un rendement élevé. Au moins un dispositif mélangeur discontinu (101) est combiné à au moins un dispositif mélangeur continu (106) à arbres multiples comportant un nombre important d'arbres. Par exemple, le dispositif mélangeur continu à arbres multiples peut être une extrudeuse annulaire possédant une pluralité de vis corotatives disposées en forme d'anneau. En service, un premier composé élastomère (104) est déchargé dudit ou desdits dispositifs (101) mélangeurs discontinus et traité avec ledit ou lesdits dispositifs (106) mélangeurs continus à arbres multiples, ce qui donne un second composé élastomère (108).
