Title (EN) PROCESS FOR PRODUCING AN ELASTOMERIC COMPOUND
(FR) PROCÉDÉ DE PRODUCTION D'UN COMPOSÉ ÉLASTOMÈRE
Abstract:
(EN) Process for producing an elastomeric compound (108) comprising at least one elastomeric polymer (102) and a reinforcing filler (103), comprising at least one step of feeding at least one batch mixer (101) with at least part of elastomeric polymer and at least part of reinforcing filler, the batch mixer including a mixing chamber, a pair of rotors and a pair of pistons movable to and from the pair of rotors; thereafter, at least one mixing step in the batch mixer so as to obtain a batch of elastomeric compound (108); thereafter, a step of completely unloading the batch of elastomeric compound; thereafter, a step of feeding a twin-screw conical mixer (201) having a mixing chamber (202) accommodating two counter-rotating screws (205) converging towards an outlet mouth, and a door (206) for closing and opening the outlet mouth; thereafter, a step of mixing the batch of elastomeric compound in the twin-screw conical mixer with the door closed; thereafter, unloading the batch of elastomeric compound from the twin-screw conical mixer with the door open.
(FR) L'invention concerne un procédé de production d'un composé élastomère (108) comprenant au moins un polymère élastomère (102) et une charge de renfort (103), comprenant au moins une étape d'introduction dans au moins un mélangeur discontinu (101) d'au moins une partie du polymère élastomère et d'au moins une partie de la charge de renfort, le mélangeur discontinu comprenant une chambre de mélange, une paire de rotors et une paire de pistons mobiles depuis la paire de rotors et en direction de cette dernière; par la suite, au moins une étape de mélange dans le mélangeur discontinu afin d'obtenir un mélange de composé élastomère (108); ensuite, une étape de déversement complet du mélange de composé élastomère; puis, une étape d'introduction dans un mélangeur conique à double vis (201) doté d'une chambre de mélange (202) logeant deux vis contrarotatives (205) convergentes vers une ouverture de sortie, et une porte (206) pour fermer et ouvrir l'ouverture de sortie; ensuite, une étape de mélange du mélange de composé élastomère dans le mélangeur conique à double vis, la porte étant fermée; puis, le déversement du mélange de composé élastomère depuis le mélangeur conique à double vis, la porte étant ouverte.
