Filler dust feeder for asphalt plants
Ensure consistent asphalt mixture quality by efficiently feeding and conveying hot and cold filler dust within your asphalt plant.

The THF-TCF Filler Dust Screw Feeders and Conveyors, engineered by WAMGROUP, specialize in efficiently moving fine powders such as filler dust in asphalt mixing facilities. These screw feeders and conveyors are designed without intermediate bearings, minimizing blockage risks and ensuring smooth operations. Built from durable carbon steel, each unit features a tubular trough with inlet and outlet spouts optimized for height, and helicoid screw flighting on a central pipe, seamlessly integrating with your existing system. Ideal for both feeding and conveying processes, they support continuous, high-speed production of asphalt mixtures, including hot and cold types. With a customizable, modular design and available in multiple configurations, these units accommodate diverse operational needs. They reduce overall dimensions and feature maintenance-friendly designs, with components readily available from stock. Equipped with high-efficiency WAM power transmissions and energy-efficient gear motors, they ensure robust performance while lowering operational costs.
