Asphalt Drum Mixers offers four models of portable and stationary 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. Based on conditions and type of plant, up to 50 percent of the HMA can contain recycled pavement.
ADM’s recycle bins feature a 15-ton capacity. A tapered discharge opening leads to the direct-drive belt feeder which has a five-horsepower motor, multi-ply belt, self-cleaning tail pulley and adjustable skirt boards.
To transfer RAP from the bin, the recycle system includes a heavy-duty weigh conveyor that features a channel frame and wind protection for accurate weighing. The conveyor is two-feet wide and, depending on the model, between 45- and 65-feet long. It introduces RAP to the dried aggregate mix after the heating process.
An optional lump breaker is available to break down large pieces of RAP into a useable size. Single- and double-deck scalping screens are also available to ensure oversized material does not enter the aggregate mix. Other options include air cannons, grizzlies, bin extensions, adjustable legs with sand shoes, and a skid with bolt-on support legs.
