Astec Double Barrel® XHR Drum Mixer
The Double Barrel XHR system runs mix with up to 65% RAP
Overview
The Double Barrel XHR system runs mix with up to 65% RAP*
The Astec Double Barrel XHR achieves a quality high RAP mix. To achieve this quality mix, it utilizes both an outer chamber on the drum and an external mixer with the addition of the V-Pac™ Stack Temperature Control System to maintain as low an exhaust temperature as possible when running high RAP content. A stainless-steel drum and stainless-steel combustion flights withstand the higher temperatures associated with running high RAP. The Astec warm mix system comes standard on all Double Barrel XHR mixing systems.
*65% RAP based on 5% RAP moisture
Features
Outer Mixing Chamber
Astec’s Double Barrel XHR achieves a high RAP mix by utilizing both an outer chamber on the drum and an external mixer.
Thorough Mixing Zone
The external mixer vigorously mixes virgin liquid asphalt cement, as well as other admixtures.
V-pac Stack Temperature Control System
Astec’s V-Pac Stack Temperature Control System uses v-flights and a variable frequency drive (VFD) drum to help facilitate producing many different types of mixes, while controlling stack temperature, without the added cost and time of flight changes. Astec’s v-flights shower along the edge of its notch, as well as its tips, creating a wider veil that increases the effectiveness of the veil by exposing more material to hot gases.
Less Maintenance Cost
The cost of maintaining the Double Barrel dryer/drum mixer is comparatively low, because Astec uses proven wear materials. High-chrome, heat-treated, mixer paddle tips and wear plates in the mixing zone stand up to ton after ton of abrasive material. The burner end of the drum, as well as the mixing chamber outershell, are fabricated from a high strength, low-alloy steel for superior heat-resistance and lined with wear plates at critical wear areas.
