|Double Barrel Maintenance|
When maintenance is necessary, the well thought out design of the Double Barrel® dryer/drum mixer ensures that service can be performed quickly and easily.
Crews Appreciate Pre-Wiring
Relocatable and portable facilities are pre-wired and pre-piped for a quick and easy setup. The main power panel is centrally located in the facility, and components and wiring are designed for short cable runs, making it easier to handle cables in the field.
Access Is Safe And Easy
No other drum mixer gives you complete access to the mixing chamber from ground level like the Double Barrel dryer/drum mixer. A large door rises hydraulically for full access to the entire length of the mixing chamber allowing you to be able to service mixing shanks and tips from the outside of the drying drum shell. A separate, smaller access door allows quick inspection of the mixing chamber. The interior of the dryer drum is reached through an access door at the inlet breeching. Key maintenance items on the burner, unlike those on a conventional counter-flow mixer, are located outside. They stay cool and are easily reached for service or inspection.
Lower Your Maintenance Cost
The cost of maintaining the Double Barrel dryer/drum mixer is comparatively low because Astec uses proven wear materials. Ni-hard 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 is fabricated from Cor-Ten®, a high-strength, low-alloy steel for superior heat resistance. The mixing chamber is made from structural-quality carbon steel and lined with 3/4-inch Ni-Hard wear plates.
