An asphalt roofing material recycling system and method is used to recycle asphalt materials, such as asphalt shingles and tar paper that include granules, fibers or other particles. The asphalt material is simultaneously heated and milled in a heated milling apparatus, such as a heated ball mill (20), to reduce the asphalt material granules to a fine mesh in suspension in liquid asphalt. Excess moisture is removed from the asphalt material being recycled, either during heating and milling by continuously venting the heated milling apparatus, or before the heating and milling in a drying apparatus. The rotatable milling vessel includes a plurality of mixing members (32). The recycling system also includes a storage apparatus (16) and a filter apparatus (18).
L'invention concerne un système et une méthode de recyclage de matériaux de couverture bitumineux tels que les bardeaux bitumés et le papier goudronné qui contiennent des granulés, des fibres ou d'autres particules. On chauffe et, simultanément, on broie les matériaux bitumeux dans un appareil de broyage chauffé tel qu'un broyeur de boulets (20) afin de réduire les granulés de matériau bitumeux en grains fins se trouvant en suspension dans du bitume liquide. L'excès d'humidité dans le matériau bitumeux à recycler est évacué soit lors du chauffage et du broyage, par ventilation en continu de l'appareil de broyage chauffé, soit avant le chauffage et le broyage, dans un appareil de séchage. Le réservoir de mélange rotatif comporte plusieurs dispositifs de mélange (32). Le système de recyclage comprend également un appareil de stockage (16) et un appareil de filtration (18).
