WAM THF/TCF Filler Dust Screw Feeders and Conveyors

Specialised for handling filler dust in asphalt plants

The THF/TCF Screw Feeder and Conveyor range for Filler Dust is a specialised product line for the Asphalt Mixing industry.


THF/TCF Screw Feeders and Conveyors for Filler Dust are designed to match the main requirements of the asphalt industry in feeding and conveying both hot and cold filler dust in stationary asphalt plants, at one end from the central dust filter and at the other end from the storage silos to the weigh hopper of the mixing plant.

THF/TCF Filler Dust Screw Feeders and Conveyors are highly versatile, offering numerous solutions for feeding or conveying fine, dusty powders. Wide spans are reached in a piggyback configuration. Thanks to the modular structure of the screws, various solutions are possible in terms of performance and component configuration.

THF/TCF are manufactured from carbon steel with a suitable surface finishing. They are made up from a tubular trough equipped with at least one inlet and outlet spout, a welded flange at each tube end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end, two end bearing assemblies complete with self-adjusting shaft seal suitable for filler dust. This type of screw, which comes without intermediate bearings, is equipped with a gear motor that suits the application.
