Process for the production of rubber granules deriving from End of Life Tires, subsequently referred to as ELTS, suitable for the devulcanization process through a thermal-mechanical process, wherein said ELTs are selected from truck tires and/or agricultural vehicles and/o earth-moving machinery and/or cars and/or light transport vehicles, the process comprising the following steps: - selection of the ELTs to be treated, said selection step consisting in the selection of tires that do not show oxidation and do not show a phenomenon of saponification and evident deterioration, old production tires having to be discarded where there is a doubt about the presence of aromatic amines therein; - coarse crushing of the tire to create a shredded ELT, said coarse crushing step being carried out through a mechanical process which reduces the tire into coarse pieces, preferably with a size varying between 10 and 20 cm; - volumetric reduction of shredded ELT for the production of raw rubber granules, said step taking place by means of at least one mechanical granulator, which, through -the passage of rollers equipped with blades, determines the volumetric reduction and allows the separation from metals and any fibers textiles and/or plastics, as they are crushed and separated from the rough rubber granules, in order for polymer degradation not to occur, this mechanical granulator being refrigerated to prevent from reaching a temperature greater than 40 °C; - separation of the granules through a system of vibrating densimetric tables, and with the help of aimed air jets, which separate the granules based on their mean specific weight, thereby obtaining: * removal of metals from said raw rubber granules; * elimination of any textile and/or plastic fibers from said raw rubber granules; and - selection of rubber granules based on size; - curing of rubber granules by arranging the rubber granules in containers placed in a closed warehouse, preferably at a constant temperature of about 20°C, with forced aeration and washing of air through a column that acts with sodium hypochlorite and soda, preferably for a period of at least 45 days, to obtain a maturation of the granules. - selection of the ELTs to be treated, said selection step consisting in the selection of tires that do not show oxidation and do not show a phenomenon of saponification and evident deterioration, old production tires having to be discarded where there is a doubt about the presence of aromatic amines therein; - coarse crushing of the tire to create a shredded ELT, said coarse crushing step being carried out through a mechanical process which reduces the tire into coarse pieces, preferably with a size varying between 10 and 20 cm; - volumetric reduction of shredded ELT for the production of raw rubber granules, said step taking place by means of at least one mechanical granulator, which, through -the passage of rollers equipped with blades, determines the volumetric reduction and allows the separation from metals and any fibers textiles and/or plastics, as they are crushed and separated from the rough rubber granules, in order for polymer degradation not to occur, this mechanical granulator being refrigerated to prevent from reaching a temperature greater than 40 °C; - separation of the granules through a system of vibrating densimetric tables, and with the help of aimed air jets, which separate the granules based on their mean specific weight, thereby obtaining: * removal of metals from said raw rubber granules; * elimination of any textile and/or plastic fibers from said raw rubber granules; and * removal of metals from said raw rubber granules; * elimination of any textile and/or plastic fibers from said raw rubber granules; and - selection of rubber granules based on size; - curing of rubber granules by arranging the rubber granules in containers placed in a closed warehouse, preferably at a constant temperature of about 20°C, with forced aeration and washing of air through a column that acts with sodium hypochlorite and soda, preferably for a period of at least 45 days, to obtain a maturation of the granules.
