Ammann drum mix plant handles asphalt production and high-capacity recycling

A new counterflow drum mix plant from Ammann is designed for high production and high-capacity recycling. The Ammann Alpine Drum Mix is available in stationary, relocatable, and portable configurations that range from 300 to 600 tons per hour.

HMA producers can use the Alpine series mix plant for high total production and amount of recycled asphalt (RAP) content without sacrificing mix quality, using Ammann's controls and technologies. The control system is extremely intuitive, allowing tracking and analysis of plant operating data in real time, which allows for efficiency improvements.

The new plant features a single drum, multi-zone drying and mixing system with VFD, increasing performance and flexibility. It features modular and scalable design components, and has RAP capabilities of up to 60 percent. It has warm asphalt capability using Ammann's Foam system

The plant is easy to customize and retrofit to existing facilities. Extreme wear packages are available for extended operating life.

Ammann's HMA storage silos have capacities that range up to 300 tons, with extended mix storage options available. Silos are engineered with expansion in mind. The modular silo batcher arrangement is expandable and optimal for retrofitting.

Ammann's aggregate feed systems include troughing feed belts, and large bin openings allow for more capacity. Steep, sloped bin walls optimize material flow, while variable frequency drives promote simple, accurate calibration and production changes.
