|Double Barrel Total Control|
The Astec Double Barrel® drum mixer and control system are designed to move aggregate effortlessly through the mix process with maximum efficiency.
Free Flow Into The Drum
The drying process begins when the virgin aggregate enters the inner drum through a rubber seal and gravity chute. The seal restricts air entry into the drum while allowing the aggregate to pass through. The angle of the clad lined inlet chute keeps material flowing freely into the drum.
Flights Serve Three Functions
Three different types of flights move the material through the drying chamber. They are especially designed for three separate functions.
Measure Actual Temperature
Once heated and dried, the aggregate leaves the drying chamber and enters the mixing chamber.
At this point, an infrared sensor measures the temperature of the hot aggregate and automatically adjusts burner output to keep aggregate at the required temperature.
This unique Astec feature makes it easier for you to control mix temperatures and to turn out mixes that conform to specifications.
TCII or PMII systems control and monitor proportional control of aggregate feeders and the blending of asphalt, recycle, shingles, and additives. Both systems work with WM2000 which controls silo load out, inventory, and sales transactions. Upgrade to TCII controls for more flexibility and expansion options.
