Abstract: An asphalt drum drying and mixing plant capable of using recycled pavement aggregate material includes two interacting drums, each being heated to different temperatures. A first drum is a parallel flow drying and mixing drum. The recycled material is introduced at the intake or feed end of this first drum and dried and heated to a comparatively low temperature in a first region of the first drum. A burner of relatively lower heat generation capacity furnishes heated gases. The recycled material is protected by supplying the gases through a cylindrical combustion chamber within which the fuel is completely burned such that no luminous gases enter the drum and contact the recycled material. A second, adjacent region of the parallel flow drum is the mixing region. The recycled material is transferred to the mixing region with close control over the temperature at which the material enters the mixing region. The parallel flow drum also has an intermediate feed chute through which virgin aggregate material is added. The virgin aggregate is heated in a counterflow drum to a temperature higher than the recycled material and the temperature of the final mix is controlled by changing the temperature of the virgin material. The exhaust from the mixing region is introduced as secondary air into the counterflow drum burner assembly. From the counterflow drum all gases are passed to a cleaning system including a cyclone separator and a baghouse filter. From the cyclone separator and the baghouse filter separated material and fines are routed into the mixing region together with liquid asphalt cement.

Abstract: In a dryer apparatus including an elongated rotatable drum having an input end and an output end, a burner for directing hot gases into the input end of the drum, and an aggregate feed mechanism for supplying aggregate particles into the drum adjacent the input end and for conveying the aggregate particles toward the output end, an assembly adapted to introduce reclaimed asphalt pavement particles into the dryer includes an inner drum for introducing reclaimed asphalt pavement particles into the elongated drum at a position adjacent the output end of the elongated drum and for moving the recycled asphalt pavement particles within the elongated drum in a direction counter to the direction of flow of the hot gases so that the hot gases heat the recycled asphalt pavement particles during travel of the recycled asphalt pavement particles within the inner drum assembly. The inner drum is mounted for rotation with the elongated drum and has an inlet end, an outlet end, and flighting for moving the recycled asphalt pavement along the inner drum from the inlet end toward the outlet end such that recycled asphalt pavement falls from the outlet end of the inner drum into the elongated drum and mixes with aggregate particles which are introduced into the drum adjacent the input end. The particles are heated by the hot gases moving in and around the inner drum as well as by conduction heating carried out via the flighting within the inner drum.

Abstract: A drum mixer is provided for producing an asphaltic composition. The drum mixer utilizes a first heat source located at an intermediate position within the drum mixer for producing a first current of hot gases directed towards the entry end of the drum mixer. The drum mixer also utilizes a second heat source located at the discharge end of the drum mixer for producing a second current of hot gases directed towards the entry end. Virgin aggregate is introduced into the drum mixer at the entry end of the drum mixer and is heated by the first current of hot gases. Recycle material is introduced into a mixing zone within the drum mixer between the first heat source and the discharge end. The heated virgin aggregate combines with the recycle material in the mixing zone and is further heated by the second heat source. Liquid asphalt is mixed with the virgin aggregate and recycle material in the mixing zone and the product is removed from the drum mixer at the discharge end.

Abstract: A combustion housing for surrounding a burner flame is provided at an intermediate location within a drum mixer. An annulus is formed by the combustion housing and the interior of the drum adjacent thereto. Hot virgin aggregate is mixed with cold recycle material within the annulus. The mixing materials are further heated by conduction from the combustion housing surface and extending structures extending from the combustion housing into the annulus. The combustion housing is also provided with a plurality of openings for allowing radiant heat to enter the annulus and heat the mixing materials and for circulating combustible by products of asphalt production into the combustion housing for burning.

Abstract: The present invention relates to a continuous drum dryer mixer apparatus and method for heating and drying virgin aggregates, as well as recycled asphaltic pavement materials and mixing such materials with liquid asphalt cement and other ingredients to formulate asphalt paving materials.A first cylindrical rotatable drum dryer has a first material input in one end thereof and a material output at the other end thereof. The output is directable at the option of the operator to either a hot elevator for carrying it to an asphalt batch plant or into a second concentric or offset rotating drum mixer. A burner is mounted either at the output end of the first cylindrical drum, or at the output end of the second drum and extends therethrough to the output end of the first cylindrical drum for directing a flame into the first cylindrical drum. A liquid asphalt injection nozzle introduces liquid asphaltic materials into the second cylindrical drum Mixer for mixing with dried aggregates and recycled asphaltic materials. The device also includes a first suction device which cooperates with two annular plates to prevent smoke and fines from passing from the mixing drum to the heating and drying drum. A cowling, fan and connecting pipe are used to recirculate the hot exhaust gases back to the burner.

Abstract: 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.
