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 and at least two mixing and cooling installations that perform a mixing and cooling process;
• a feed belt that directs a rubber mixture from the initial mixing installation to at least one of two mixing and cooling installations;
• and
• a transport means that sequentially directs the rubber mixture to at least one rubber mixing installation according to a rubber mixture recipe selected for producing a rubber mixture having expected properties,
• wherein each mixing and cooling installation comprises at least one spray system in which one or more spray rails are positioned at each of an upper spray station and a lower spray station, each spray rail being in communication with a source for supplying water and air to one or more nozzles at a predetermined water flow rate and a predetermined air pressure.
