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.

Abstract: A dryer drum coater reduces blue smoke emissions by evacuating the blue smoke from the dryer drum coater independently of the exhaust of combustion products. The blue smoke, produced when heated and dried aggregate is mixed with other asphaltic products such as RAP or liquid asphalt, is preferably evacuated from a vapor outlet formed remote from the exhaust products outlet of the coater and adjacent the heated and dried aggregate inlet of the mixing chamber. Evacuating the blue smoke at this location obviates the need to separate the blue smoke from the combustion products and also prevents the introduction of excess oxygen into the combustion zone of the dryer drum coater. In a particularly preferred arrangement, the evacuated blue smoke is fed directly to the combustion air inlet of the coater's burner blower and is thereby incinerated.

Abstract: A dryer for use in an asphalt plant for heating and drying virgin aggregate and also pre-heating reclaimed asphalt products (RAP). A drying drum cylinder having a burner at one end heats and dries virgin aggregate traveling therethrough. A second cylinder near the burner surrounds the drying drum and creates an annular cavity. RAP is introduced and travels through the annular cavity and exits adjacent the drying drum aggregate exit opening. Heat given off by the drying drum increases the temperature within the annular cavity and heats the RAP traveling therethrough. Heated aggregate and RAP first come in contact with one another after exiting the annular cavity and the drying drum and are, thereafter, delivered to a mixing drum.

Abstract: A rotary drum dryer has devices for cooling shielding flights located in the combustion zone of the drum. The devices comprise cooling flights which rotate with the drum to scoop up relatively small amounts of virgin aggregate from aggregate accumulated in the lower portion of the drum and to shower this aggregate over the outer radial surface of the shielding flights upon further rotation of the drum, thereby cooling the shielding flights without substantially decreasing the mean temperature of the aggregate. Cooling efficiency is enhanced by the continuous cascading of fresh aggregate over the shielding flights from the cooling flights through a substantial portion of the drum's rotation. The cooling flights and shielding flights preferably cooperate to limit or even prevent the showering of materials into the burner flame and thus inhibit burner flame quenching and accompanying emissions. Particularly preferred cooling flights take the form of auxiliary flights which can be easily adapted to existing shielding flight designs.
