System and method for producing rubber mixtures for tires

A system for producing rubber mixtures having expected properties comprising:

• a series of rubber mixture production installations that define monopassage and multipassage sequences of rubber mixture production, each rubber mixture production installation permitting execution of at least one rubber mixture production process, and the rubber mixture production installations including at least one initial mixing installation that performs an initial mixing process;
• a first mixing and cooling installation that performs a first mixing and cooling process before a complementary mixing process;
• at least one complementary mixing installation that performs the complementary mixing process;
• a second mixing and cooling installation that performs a second mixing and cooling process after the complementary mixing process;
• and
• a transport means that sequentially directs the rubber mixture toward either the complementary mixing installation or toward the second mixing and cooling installation according to a rubber mixture recipe selected for producing a rubber mixture having the expected properties.
