The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
The Six Pack Asphalt Plant Sets the Standard for Portability and Productivity.
With its 1983 introduction, the Astec Six Pack plant started a revolution in the asphalt pavement industry as the first truly portable asphalt mixing plant available to producers. Since then, it has been established as a superior portable asphalt plant.
The standard setup comes with the 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 with ductwork, dust screws, electrical switch gear, cables, and plant controls. Astec also supplies RAP bins, fuel tanks, lime mixers and AC tanks. There are a wide range of options on these compact, maneuverable plants. With a team of experienced engineers and in-house technicians, Astec has the knowledge and the expertise to help you make the appropriate selections to meet your requirements.
Astec Six Pack
Applications
Asphalt Mixing
A thermal mixing process is required to turn aggregates and liquid AC into an asphalt pavement mix for road construction. This makes an asphalt mixing plant necessary for road construction. The complete line of Astec asphalt mixing plants, and its range of capacities and features, gives you the choices and flexibility to create your optimum solution.
The NTEP certified underslung load cell mounts provide accurate and reliable weighing and load-out performance. The underslung mounting feature ensures precise and stable bin positioning to achieve easy calibration and steady scale response.
Batcher
A four-ton (3.6 metric ton) batcher is installed at the top end of the Astec SEB's drag conveyor. It collects the mix discharged from the drag conveyor. Segregation is minimized by dropping full batcher loads into the surge bin.
Cable Trays
The Six Pack plant locates the main power panel and the junction box for control house wiring in the middle of the plant. This central location for the panels keeps cable runs short. The tray-rated cables with quick disconnects make for fast electrical hook-up and quick packing when moving to another site. Cable trays are fitted to each load, keeping cables organized and off the ground.
SES (Self-Erecting Silos)
The optional Self-Erect Silo (SES) can be set up and leveled in about 2.25 hours from the moment the truck is unhooked. The only additional equipment required for setup is a front-end loader. Most actions are accomplished through hydraulics integrated in the unit and pumped for instant operation. The silo, drag, reject chute and leveling system are all run by the onboard hydraulic unit.
To gain higher ground clearance for movement on uneven surfaces, the SES frame can be hydraulically raised to add spacer blocks in axles.
The drag transports on the silo load for easy travel. A batcher atop the drag collects finished mix before depositing it in the self-erect silo.
Recycle (RAP) Bins
The portable RAP system includes everything for metering recycled material into the mix. The system includes belt feeders, collecting conveyor with weigh bridge, scalping screen, inclined conveyor to the drum, and up to four bins. The foundation plates are lowered into position and the conveyor is raised hydraulically. Just like the cold feed unit, the RAP system is equipped with built-in tubular steel foundations and bulkheads.
Air Bag Suspension
Astec portable equipment comes with air bag suspensions that protect components from damage caused by rough rides on the highway. The system automatically adjusts for the smoothest ride and allows height adjustments for bridge and ground clearances. Using the air bags to pre-level loads before lowering the foundations helps speed setup. Compare Astec suspensions to others. No one else gives you a system of such quality.
Cold Feed Bins
Pull the cold feed into position at the site. Lower the thick tubular steel foundations into place to support the portable cold feed unit. All belt feeders and the collecting conveyor are included. The inclined end of the collecting conveyor discharges onto a transfer conveyor feeding screen. Built-in, hinged bulkheads swing into operating position in minutes. Pre-installed, optional bin partitions and grizzlies fold down for transport.
Baghouse Options
Only Astec provides a choice of two distinct baghouse styles, pulse-jet and reverse-pulse. The baghouse load contains all necessary ducting. Slip joints compensate for differences in component alignment to make setup easy.
Portable Mixing Drum Options
Only Astec offers three exclusive mixing systems.
The Six Pack drum load includes the burner, burner platform, inlet breaching and the duct transition to the primary collector. Plate foundations support the load. Built-in jacks make final leveling adjustments easy, so the Six Pack plant can start running sooner.
