Nomad™ Asphalt Plants
Nomad plants are available in three sizes, designed for maximum production capacities of 72, 118, or 159 metric tons per hour (80, 130, or 175 TPH). Intended for portability, durability, and reliability, Nomad plants meet the demands of a variety of small, medium and large projects that require quality hot mix asphalt.
Voyager™ Asphalt Plants
The Voyager 120 offers a compact, highly portable design. Unique for a plant in this class with the ability to run up to 30% RAP. In addition, it is backed by the best service support in the industry.
The ASTEC Voyager 120 is built around a counter flow drum featuring ASTEC v-fights. The v-flights provide greater uniformity of the aggregate veil during the drying process, which results in better heat transfer, a reduction of fuel use and increased productivity.
Six Pack® Asphalt Plants
The latest standard Six Pack portable HMA plants come with a Double Barrel® drum mixer, cold feed, scalping screen with inclined conveyor, baghouse, surge bin, drag conveyor and control house. The baghouse load also holds the inertial dust collector. One load handles the SEB and drag conveyor. All ship complete with duct work, dust screws, electrical switch gear, cables, and plant controls. We also supply RAP bins, fuel tanks, lime mixers and AC tanks.
M-Pack™ Asphalt Plants
Astec designed a facility for customers who don’t need to move often and still want to reap the benefits of faster and more economical setup. The M-Pack is engineered as a set of modules, which are transported by truck and bolted up at the site. Astec tests each component before shipping it to your site to ensure a hassle free setup. Plus, the M-Pack gives you full-size control rooms, large silos, high production capacity, and excellent maintenance access.
Stationary Drum Plants
Astec stationary plants are suitable for permanent installations, especially when the highest production volumes are required. They allow flexibility for future add-ons as the needs of the contractor change. Stationary plants can accommodate unconventional plant layouts.
Components are supplied with steel legs to grade. Concrete foundations hold the legs and support the components.
Stationary plants are outfitted with Double Barrel® drum mixers and storage silos are used to hold the mix. Like Astec portable and relocatable plants, Astec stationary plants are equipped with many, innovative features not available anywhere else. Astec pollution and noise control equipment include load out tunnels, systems that capture hydrocarbon vapors, stack silencers, and burner blower silencers. This technology makes these permanent facilities good neighbors in their communities.
Astec leads the way with attractive, stationary asphalt plants that offer clean, trouble-free operation.
Stationary Batch Plants
The batch plant is ideal for metropolitan areas requiring a large number of different mixes. Instead of a continuous mixer, these facilities use a batch tower. Bins in the top section of the tower hold dried aggregate in various sizes. Depending upon the mix needed, the bins automatically dispense the correct amount of the required aggregate. The dry material is routed to a pugmill mixer located at the bottom of the tower. Here the liquid asphalt is added. After thorough mixing, the bottom of the mixer opens and the batch is dispensed into a truck or conveyed to a storage silo.
Depending on the model Astec batch plants produce 45 to 500 tons of HMA per hour. Three model series are offered: TS, Super and BGA. Super towers and TS towers are similar in design. The larger Super tower includes extra-large aggregate bins. BGA towers are based on the proven Barber Greene design for which Astec retains all rights. BGA models are smaller in size.
Astec batch plants are the most modern, most rugged and most dependable in the world.
Recycle Batch Plants
A uniquely designed batch plant is offered in the full range of batch plant sizes with varying volumes of hot bin storage. With this design, recycled material is blended with the superheated, virgin aggregate in the bucket elevator and is conveyed to the top of the tower. This allows the operator the versatility to process recycle percentages from 0% to 40% and switch from recycle mixes to virgin mixes without emptying the hot bins.
Batch Drum Plants
A Double Barrel® mixer can be set up in combination with a batch tower for maximum versatility. This enables the facility to produce a variety of batch mixes and high volumes of continuous mixes using RAP. The counterflow dryer section of the Double Barrel dries all the aggregate. A special diverter gate routes the aggregate leaving the dryer section. Astec storage technology added to the plant gives the producer the possibility to sell a wide range of HMA products.
Coater II Plants
A batch plant with an Astec Coater II can run two HMA production lines, one mixing in batches and the other in continuous runs. The dual-shaft Coater II comes in nine different sizes. Coaters can produce up to 725 tons per hour. These facilities are also outfitted with either a surge bin or a storage silo, a diverter chute for the dryer, weigh bridges for the cold feed bins, and related controls. Existing batch facilities can be retrofitted with the coater as a stand-alone unit.
