Production of rubber mixtures in a rubber mixture production line incorporating one or more twin-screw mixing and extrusion machines

A rubber mixture production line (100, 100′) comprising an internal mixer (MI) that performs a masterbatch manufacturing process from materials comprising elastomeric material and additional materials, the rubber mixture production line (100) comprising:

• at least one hot mixing line (102) disposed downstream of the internal mixer (MI) and comprising at least one twin-screw mixing machine (BXc) that performs a mixing process of the rubber mixture exiting the internal mixer (MI);
• at least one cold mixing line (104) disposed downstream of the at least one hot mixing line (102) and comprising at least one twin-screw mixing machine (BXF) that performs a mixing process of the rubber mixture exiting the at least one hot mixing line (102);
• a batch-off installation (BO) disposed downstream of the at least one cold mixing line (104) that performs an anti-sticking and cooling process of the rubber mixture exiting the at least one cold mixing line;
• and
• an end-of-line installation (FL) disposed downstream of the batch-off installation (BO) that performs one or more end-of-line processes of the rubber mixture.
