Abstract
A system and a method are provided for producing rubber mixtures. The system includes installations for performing a monopassage process and a multipassage process to produce a rubber mixture, and a transport system that transports the rubber mixture to one or more of the installations according to a selected recipe. The installations include a mixing and cooling installation that performs a mixing and cooling procedure in which the rubber mixture is formed into a sheet, the sheet is sprayed with water using at least one nozzle provided with water at a predetermined water flow rate and air at a predetermined air pressure, and evaporated water from the spraying of the sheet is evacuated at a predetermined air flow rate. The mixing and cooling procedure causes the rubber mixture of the sheet to reach target temperature and water-content values before a complementary mixing procedure is performed.
