Astec Double Barrel® X Drum Mixer

Overview

Drum Dryer with External Mixer

The Double Barrel X system separates the drying process from the mixing process, thereby providing a very reliable tool to be used for the purpose of recycling reclaimed asphalt pavement (RAP). With a Double Barrel X system, a plant can process both warm and hot asphalt mixes with up to 50% RAP content while maintaining zero opacity at the stack.

The Double Barrel X technology allows for RAP to be pre-conditioned through the external part of the DBX dryer, flashing off moisture in the drum, thus eliminating the problems associated with scavenger systems.
