Abstract

L'invention concerne un dispositif pour la fabrication de produits enrobés bitumineux à partir d'agrégats, de bitume et de matières solides susceptibles de se dégrader à tempé­ rature élevée. The invention relates to a device for manufacturing bituminous coated products from aggregates, bitumen and solids likely to degrade over time high erasure.

Le dispositif est constitué par un tambour (1) rotatif. Les matériaux solides et les gaz chauds venant d'un brûleur (6) circulent dans le même sens. Le tembour comporte une zone d'introduction (16), une zone de transfert (17, une zone intermédiaire (18) et une zone de malaxage à chaud (19) des agrégats et des matières bitumineuses. La zone intermé­ diaire (18) comporte une première partie où des aubes rele­ veuses (28) disposées sur la paroi interne du tambour (1) permettant la constitution d'un rideau continu de matériaux dans toute la section du tambour (1) et une deuxième partie où sont introduites les matières solides dégradables à haute température. Dans cette deuxième partie, le tambour (1) comporte une second enveloppe (31) interne coaxiale à son enveloppe externe (1), garnie intérieurement d'aubes rele­ veuses (32). The device consists of a rotary drum (1). The solid materials and hot gases from a burner (6) are going in the same direction. The drum has a zone introduction (16), a transfer area (17, an area intermediate (18) and a hot mixing zone (19) of the aggregates and bituminous materials. The intermediate zone diaire (18) has a first part where vanes link veuses (28) arranged on the internal wall of the drum (1) allowing the constitution of a continuous curtain of materials throughout the drum section (1) and a second part where high degradable solids are introduced temperature. In this second part, the drum (1) comprises a second internal envelope (31) coaxial with its outer casing (1), internally lined with reles veuses (32).

L'invention s'applique en particulier à la fabrication de produits enrobés pour usage routier, à partir de matériaux recyclés. The invention applies in particular to the manufacture of coated products for road use, from materials recycled.
