Asphalt Drum Mixers offers four models of portable and stationary recycle systems to enhance asphalt plants’ cost efficiency.
The recycle systems allow plants to use milled material in hot mix asphalt (HMA). Since recycled asphalt pavement (RAP) is much cheaper than virgin aggregate, the result is a less expensive finished product that maintains the high quality of a pure virgin aggregate mix, the company says.
Asphalt Drum Mixers’ 15-ton-capacity recycle bins feature continuously welded seams. The company reinforces the bins with angle irons and midsection stiffeners and incorporates steeply sloped sidewalls to prevent material from plugging or bridging. A tapered discharge opening leads to the direct-drive belt feeder, which includes a 5-hp motor, multi-ply belt, self-cleaning tail pulley and adjustable skirt boards.
The recycle system transfers RAP from the bin with a heavy-duty weigh conveyor that features a channel frame and wind shroud protection for accurate weighing. The conveyor is 2 ft. wide and, depending on the model, between 45 and 65 ft. long. The system introduces RAP to the dried aggregate mix after the heating process. As much as 50 percent of the HMA can contain recycled pavement, depending on the conditions and type of plant, Asphalt Drum Mixers says.
Portable units feature a heavy-duty I-beam frame on a gooseneck trailer with a fifth-wheel kingpin hitch, single axle and air brakes. The trailer includes hinged support legs and a hydraulically-controlled incline conveyor.
