Filler dust screw feeders for asphalt plants
Optimize your asphalt production with precise filler dust handling, ensuring seamless integration from dust collection to weigh hoppers.

Feeds and Conveys Filler Dust in Asphalt Mix
The THF-TCF Filler Dust Screw Feeders & Conveyors from WAMGROUP are engineered specifically for the asphalt industry, optimizing the handling of filler dust with precision. These robust conveyors efficiently transport both hot and cold filler dust from central dust filters to storage silos and then to weigh hoppers in mixing plants. Crafted from carbon steel with a durable surface finish, the system includes a tubular trough with inlet and outlet spouts and helicoid screw flighting for seamless operations without intermediate bearings. With a modular design that supports various performance configurations and components available from stock, it offers flexibility for custom setups and easy integration into existing production lines. Engineered for continuous, high-speed operations, it meets the demands of asphalt plant processing and construction site requirements. Maintenance is simplified with a design that minimizes downtime, ensuring high operational efficiency in the transport and processing of fine, dusty powders.
