Abstract: A counter-flow drum mixer asphalt plant equipped with a secondary feeder for introducing RAP to direct radiant heat of the combustion zone. Heated virgin aggregate and RAP in the combustion zone are delivered through a transition piece to a first stage of the mixing zone where liquid asphalt is combined with the materials and secondary combustion air flows through the first stage to evacuate blue smoke and steam back to the combustion zone. The second stage of the mixing zone is substantially isolated from secondary combustion air flow where dust and mineral fines are introduced and mixed to complete the asphalt product discharged from the mixing zone. Alternative constructions of the mixing zone are disclosed to provide the first and second stages having such characteristics, as well as options for both the passive and active control of the secondary combustion air. An optional secondary burner in the exhaust housing elevates the temperature of the exhaust gas above its dew point temperature before delivery to the baghouse.

Abstract: A method for operating a counter-flow aggregate dryer for an asphalt plant in which primary aggregate materials are introduced into a first end of a horizontally rotating cylinder and travel to the second, discharge end of the cylinder through drying and combustion zones. Hot gases are generated in the combustion zone to flow in counter-current heat exchange relationship with the aggregate materials for discharge from the first end of the cylinder to air pollution control equipment. Secondary materials like RAP or virgin aggregates are fed directly into the combustion zone. The discharge gas stream is heated above its dew point prior to delivery to air pollution control equipment.

Abstract: A process for reclaiming salvaged asphalt includes feeding salvaged asphalt mixed with new sands, stones and tar in a designed proportion into a double-layer drying machine including inner and outer gyroscopic drums; indirectly heating the salvaged asphalt in the drying machine by using a plurality of burners disposed externally to dry the salvaged asphalt, the heat thus generated being recycled via a draft tube into the drying machine to further heat the salvaged asphalt until the tar in the mixture starts to soften at about 80° C.; and mixing the salvaged asphalt with tar to form rejuvenated asphalt product when they travel to the outer gyroscopic drum in which the temperature reaches and the temperature of the stones contained in the salvaged asphalt also reaches a temperature of 160° C. for fusion with the tar.

Abstract: An asphalt plant including a plurality of asphalt processing components, with a selected first set of the components producing volatile emissions and a selected second set requiring process heat energy. A central burner assembly is connected to the selected second set of components by an insulated duct system for providing heat energy to the second component set. A first duct system is adapted to capture a portion of the volatile emissions produced by the first component set and convey the captured emissions into the central burner for mitigation. The central burner is preferably a media burner incorporating flameless combustion technology as well as an adjustable internal fuel injection system, which results in safer and more controllable combustion. Even with captured fugitive emissions in the inlet air, the fuel injection system keeps the concentration of combustible materials well below the lower flammability limit.

Abstract: The counterflow drum mixer includes an elevated virgin aggregate inlet end and an opposite asphaltic product discharge end. A burner lies intermediate the ends and defines a combustion volume. Shield flights surround the combustion volume defining an annular chamber with the drum wall. Recycle material is supplied to the annular chamber at the upstream end of the combustion volume for heating by convection and conduction in the annular chamber. The virgin aggregate material flows through a drying zone, into the combustion volume and between the shield flights into the annular chamber for contact with and conductive heating of the recycle material. Radiant heat transfer from the combustion volume along radii of the drum to the annular chamber is prevented. Virgin aggregate and recycle material in the annular chamber is prevented from entering the combustion volume by the shape of the shield flights and the rotation of the drum which enables the virgin aggregate in the combustion volume to shield the recycle material from radiant heat. The combined virgin aggregate and recycle material is mixed with liquid asphalt in the mixing zone to form the asphaltic product.
