Astec UniDrum^® Drum Mixer

Overview

The UniDrum mixer offers asphalt pavement producers a heavy-duty drum that generates high quality mix.

The UniDrum is a high quality counterflow design that is offered in both portable and stationary arrangements. The UniDrum mixer is offered as part of complete new plants and also for retrofit applications, with a range of production capacities from 200 to 600 tons per hour (182 to 544 tonnes per hour) with 5% moisture.

With an extra-long drum, the UniDrum mixer is uniquely capable of producing quality hot mix at a high production rate with a high percentage of recycle. The extra-long drum length maximizes mixing and drying times to reduce fuel consumption and provide superior mixing.

Applications

Asphalt Mixing

A thermal mixing process is required to turn aggregates and liquid AC into an asphalt pavement mix for road construction. This makes an asphalt mixing plant necessary for road construction. The complete line of Astec asphalt mixing plants, and its range of capacities and features, gives you the choices and flexibility to create your optimum solution.

Features

UniDrum Slinger Feeder

Optional slinger feeder transfers aggregate directly to the UniDrum dryer.
Unidrum Recycle Inlet

A collar around the drum allows entry of recycled asphalt (RAP), additives/filler, and baghouse dust into the mixing chamber, where they are blended with the virgin material.
Unidrum V-Flight Veiling

Provides greater uniformity of the aggregate veil through the gas stream during the drying process, across a wide variety of mix designs and tonnage rates.
Astec V-Flight

The v-shaped notch allows material to start pouring out of the bucket at the beginning of each revolution. The material in the bucket continues to pour out until the rotation is complete. This is what provides an even veil of material. The v-flight is also larger than a traditional flight, allowing it to carry the same amount of aggregate even with the notch.
PM III Controls

PMIII is the next generation of hot mix asphalt controls. Facility operation has never been easier, faster or more accurate than with this new, ‘hard-PLC’ based control. Expandable and retractable to suit your specific needs, PMIII puts the best of our time-tested software, along with new developments, into the most cutting edge industry hardware.
