Abstract: Apparatus and method are disclosed for processing recyclable asphalt material. A drum has a polygonal cross-sectional configuration providing a plurality of substantially flat wall sides. Tubular breaker members within the drum are juxtaposed with corresponding flat wall sides. The relative location of the breaker members and the flat wall sides effects a cascading of recyclable asphalt material over the breaker members and between the breaker members and the flat wall sides as the drum is rotated so that recyclable asphalt material is tumbled within the drum, thereby simultaneously reducing the size of relatively large pieces to aggregate-sized pieces and heating the mass containing the desired aggregate-sized pieces for delivery of the heated mass from the drum.

Abstract: A counter-flow aggregate dryer for an asphalt plant is equipped with a secondary feeder for introducing RAP or virgin materials intermediate the ends of the combustion zone of the dryer. Nonveiling flights in the combustion zone shield material carried through the combustion zone from direct radiant heat and veiling flights in the drying zone create a curtain of falling aggregates heated by a hot gas stream flowing in a countercurrent direction from a primary burner. A secondary burner elevates the temperature of the exhaust gas above its dew point temperature before delivery to the baghouse.

Abstract: A drying and mixing plant is provided comprising a tapered inner drum (1) and an oppositely tapered outer drum (4) attached together concentrically and rotated as a unit. A burner (37) directs a hot air stream into the small end (2) of the inner drum (1). Material is fed into the small end of the inner drum, where impellers (40) lift it and drop it into the hot air stream and move the material through the inner drum (1) aided by the downward taper of the inner drum. The material exits the inner drum and enters the outer drum (4) where an additive material is introduced and mixed with the material (42) as both move through the chamber (28) between the inner and outer drums to a material outlet. The receiving end (5) of the outer drum (4) is enclosed in a shroud (12), therefore the air stream is directed through the chamber (28) between the drums, the chamber having an expanding cross section which slows the air down allowing fines to precipitate out. The device may include nozzles (17) for spraying water across the path of the air stream and material flow, and further may include, for fluid additive materials, additive nozzles (21, 23) spraying the additive material across the path of the air and material. A third drum (43) may be provided inside the inner drum (1), allowing separate addition of a third material (47), and further reducing fines in the air. The device is particularly suitable for mixing asphalt paving mix.
