A method for making asphalt in such asphalt production facility.

Abstract: The invention relates to a device for manufacturing coated materials, the device comprising: a furnace comprising an enclosure (2) that is designed to be caused to rotate, that has an inside wall (2A) and that is provided with a main inlet (3) designed to receive non-coated new granular materials (25) or recycled granular materials (25) or a mixture of both of these types of granular materials, and an outlet for the bituminous coated materials that are manufactured inside the enclosure (2); heater means defining a combustion zone (4) inside the enclosure (2) and generating a drying flow suitable for drying the granular materials (25); and protective means for protecting the inside wall (2A), which means are situated in the combustion zone (4); said device being characterized in that the protective means are formed by a plurality of plates (13) that extend at some distance away from or else against the inside well (2A), and that are mutually overlapping in part so as to protect the inside wall (2A) thermall

Abstract: A device for manufacturing hot-mix coated materials includes an oven (1) having an enclosure (2) provided towards its two opposite ends with a main inlet (3) designed to receive granular materials and with a main outlet; and a heater (10) defining a combustion section (5) inside the enclosure (2). The enclosure (2) starting with the combustion section (5) and continuing with a drying section (6), and then with a mixing section (7). The device is further provided with a bypass outlet (11) and with an external mixer (12) that is connected to the bypass outlet (11), which outlet is fitted with a blocking system (15) allowing granular materials to pass towards the inlet (13) of the external mixer (12) and a closed position allowing granular materials to pass towards the mixing section (7).

Abstract: The invention relates to a mooring buoy (6), comprising a submerged part (13) and a part extending above water level (11). The part above water level comprising a fluid outlet duct (24) for attaching to a vessel (7), the buoy being anchored to the seabed via substantially taut anchor legs (27, 28). A substantially horizontally oriented fluid transfer duct (15) being attached to a connector (17) of the buoy in a non-rigid manner. The buoy comprises a substantially vertical fluid duct (21) between the connector (17) and the outlet duct (24) and a mooring connector (9) for attaching to a mooring line (8) of the vessel, wherein the length (L) of the buoy is between 20 m and 70 m and the ratio of the diameter (D) of the lower part (13) of the buoy and the length (L) being below 0.3, preferably below 0.2.

Abstract: A high pressure swivel includes an inner and an outer wall. Each annular wall is connected to a respective distribution member via apertures which have an axial dimension which is smaller than the diameter of the inlet or outlet. In this way, the pressure area between the seals of the inner and outer rotatable walls is reduced. Each distribution member may include a chamber that is defined by the external surface of the inner and outer annular walls, and an enclosing wall. In this way, an effective thermal isolation is provided by the distribution chambers adjacent to the external surfaces of the inner and outer rings. Deformation of the distribution chambers of the swivel will tend to decrease the width of the seal extrusion gap.
