Tubular Screw Conveyors
Economical & robust conveyor design for dry bulk solids.
Mechanically convey dry bulk solids with S. Howes’ robust Tubular Conveyor. Built to handle most non-liquid materials, our tubular units are significantly more robust than flexible tube conveyors. Our Tubular Screw Conveyors feature heavy-duty construction that is built to last a lifetime.
Tubular conveying models provide an economical and effective design that is ideal for single-product use.
Tubular Screw Conveyors can be tested and validated to meet your product requirements in our lab.

Tubular Conveyors – FAQs
What is a tubular screw conveyor used for?
Tubular conveyors provide enclosed conveying of bulk materials while minimizing dust generation and protecting materials from outside contamination.
What are the advantages of a tubular conveyor design?
The enclosed tube design helps improve cleanliness, contain dust, and protect sensitive materials during transport.
What materials are commonly conveyed in tubular systems?
Tubular conveyors are commonly used for powders, pellets, grains, minerals, chemicals, and other dry bulk materials.
Can tubular conveyors operate at different angles?
Yes. Tubular screw conveyors can be designed for horizontal, inclined, or vertical conveying applications depending on system requirements.
Are tubular conveyors customizable?
Yes. Systems can be engineered for specific capacities, material characteristics, and facility layouts.
