    摘要: In a process for producing asphalt-aggregate composition in which used asphaltic concrete is recycled by being heated and mixed in a rotatable drum into which flame and hot gases of combustion are directed, the improvement comprises introducing virgin aggregate in a hot zone of the drum and directly exposing the aggregate to the flame and/or hot gases of combustion, and introducing particles of asphalt-aggregate composition downstream from the hot drum input end, away from direct exposure to the flame and extremely hot gases, in a cooler temperature zone. An improved apparatus includes means for introducing the aggregate at the input drum end for direct exposure to the flame or hot-test gases, and means for introducing the used and recycled asphalt-aggregate composition in a cooler drum zone.

    摘要: A drum-type drier and/or mixer in which particulate material such as aggregate or recycled asphalt is introduced into the forward end of the drum. A burner at the rear end of the drum directs its flame forwardly through an elongated firing tube which extends from the rear end of the drum toward the forward end thereof. The hot gases discharged from the tube strike a baffle, are deflected into an annular chamber between the tube and the drum and then flow rearwardly through the chamber to an exhaust stack. The particulate material also is advanced rearwardly through the chamber and, during such advance, is heated (1) indirectly by the hot gases flowing forwardly through the firing tube and (2) directly by the hot gases deflected into and flowing rearwardly through the chamber.

    摘要: An asphalt plant adapted to use RAP to produce asphalt. The preferred asphalt plant comprises a bin that is adapted to store the RAP, a heat source that is adapted to supply heat, a dryer that is adapted to dry the RAP, a mixer that is adapted the mix the RAP and a means for conveying the RAP from the bin to the dryer. The preferred asphalt plant uses substantially only the RAP to produce asphalt. A method for producing asphalt from RAP comprising providing an asphalt plant adapted to use the RAP to produce asphalt. The preferred method further comprises conveying the RAP from the bin to the dryer, drying the RAP, and mixing the RAP.

    摘要: The present disclosure relates to industrial equipment for the hot recycling of asphalt mixes. The industrial equipment may comprise a portable bank of hoppers which may be used to meter RAP and unadulterated petrous materials and may be mounted on a supporting structure, along with gear motors which control the metering and send a signal to a flow indicator in a control panel where it may be recorded and controlled. A conveyor belt may be provided below the hopper bank in order to receive the material and transport same to a rotary cylinder comprising an industrial open-flame burner that may be used to transmit heat energy indirectly to the RAP and to the supply of unadulterated petrous material. In some embodiments, the present disclosure may also comprise: a tank for storing a mixture of asphalt and rejuvenating agent enhanced with polymers, which may be metered using a volumetric gear pump through a pipe towards the rotary cylinder, the outlet of said cylinder comprising a temperature sensor that may send a signal to the recycled asphalt mix temperature indicator in the control panel; a recycled asphalt mix lifting system which may convey said mix to a discharge silo; a combustion gas extractor which may discharge combustion gases from the burner; a fuel storage tank which may be used in the industrial burner; and a weight measuring element which may be at the inlet of the rotary drum.
