Cellulose Fiber Injection
Tarmac has developed a cellulose injection machine for hot mix asphalt plants. Stone Matrix Asphalt (SMA) and Open Graded Friction Course (OGFC) both require the inclusion of cellulose fibers to prevent drain-down of liquid asphalt in hot mix. We use a patented aggressive separator to breakup dense, 800-pound cellulose bales. A large pugmill receiver allows for the cellulose to be metered into the separator.
For dense cellulose bales, contact Interfibe.
Features
- Designed for filling using your end loader. No need for one or two men to open and dump small bags of fiber. This system was designed to take multiple 600 or 800 lb cell bulk loads, thus reducing your cost for manpower.
- Weigh depletion controls. Adding fibers via weigh depletion is the most accepted method for state requirements concerning fiber addition accuracy. Backup volumetric controls are also included.
- Removal of foreign debris. Before the fan injects fibers, the system automatically rejects stones, wet cellulose, and other foreign material before entering the blower and pipe to the asphalt plant.
- Built to Last. The Tarmac 2400 has larger metal components and drive mechanisms throughout. Wear and down time are reduced. The pug mill alone has a 6” diameter shaft with a 15 HP drive motor.
