Product Overview
The Horizontal Tubular Screw Conveyor (also known as a Pipe Screw Conveyor or Auger Feeder) is designed to solve the three biggest headaches in bulk transport: Dust Contamination, Material Spillage, and Limited Space.
Unlike U-trough conveyors which require covers, the tubular design offers a naturally fully enclosed structure. Whether you are handling fine chemical powders, food ingredients, or dusty minerals, this system ensures that 100% of your material reaches the discharge point. It effectively isolates your product from the outside environment, preventing moisture ingress and eliminating dust hazards in your workshop.
Key Capabilities:
- Handles Diverse Materials: From free-flowing dry powders and granules to semi-fluid slurries (using shaftless options).
- Flexible Routing: Can be installed horizontally, inclined, or even vertically to navigate around existing equipment.
- Space Saving: The compact circular cross-section takes up minimal floor space compared to belt conveyors.
Horizontal tubular screw conveyor is a mechanical conveyor system designed to move bulk materials from one location to another. It is a versatile and efficient method of transportation that is widely used in various industries, including agriculture, mining and manufacturing.
Typical Applications & Industries
Because of its sealed nature and material versatility, the Tubular Screw Conveyor is the preferred choice for industries requiring hygiene and containment:
- Food Processing: Transporting flour, sugar, starch, and additives using Stainless Steel 304/316 with polished finishes.
- Chemical Industry: Handling corrosive powders, fertilizers, or toxic materials where operator safety (zero leakage) is a priority.
- Agriculture & Feed: Moving grains, seeds, and feed pellets protecting them from rodents and weather.
- Plastic & Packaging: Feeding plastic granules or masterbatches into extruders or injection molding machines.
- Waste Treatment: Conveying sludge or screenings (often utilizing a Shaftless design to prevent clogging).
Typical Scenarios: Feeding packaging machines, discharging from bulk bags (Big Bags), or transferring material between processing steps.
Structure Design & Material Options
We build our conveyors to last, tailoring the construction to your specific material properties:
- A. Robust Housing Construction The conveyor body consists of a seamless steel pipe or flanged tube sections. The flange connections are sealed with industrial-grade gaskets (silicone, rubber, or PTFE) to ensure a gas-tight or liquid-tight seal.
- B. Screw Flight Options
- Solid Shaft Flight: Standard for dry, free-flowing materials. Provides structural rigidity over long spans.
- Shaftless Spiral: An open spiral without a center pipe. This is the Problem Solver for sticky, wet, or fibrous materials that tend to wrap around a standard shaft.
- C. Material Selection
- Carbon Steel (Q235/Q345): Cost-effective for general industrial use. Painted or galvanized for corrosion resistance.
- Stainless Steel (SUS304/316L): Essential for food-grade applications or corrosive chemical environments. We offer surface treatments ranging from sandblasting to mirror polishing.

Customization & Engineering Flexibility
No two plant layouts are the same. We customize the Tubular Screw Conveyor to fit your line:
- Inlet/Outlet Configuration: We can provide round, square, or flexible flange connections. Multiple inlets can be added to receive material from several bins simultaneously.
- Wear Protection: For abrasive materials, we can line the tube with UHMWPE or use hardened steel flights to extend service life.
- Integration: Designed to bolt directly onto silo flanges, mixer discharges, or connect via flexible sleeves to weighing systems.
- Cleaning Hatches: Optional inspection doors can be installed along the tube for easy maintenance and cleaning access.
Frequently Asked Questions (FAQ)
Q: Can this conveyor handle sticky materials?
A: A standard shafted screw might clog. For sticky or sludge-like materials, we recommend our Shaftless Tubular Screw Conveyor option, which eliminates the center pipe where material usually builds up.
Q: What is the maximum inclination angle?
A: Tubular conveyors are very efficient at angles. While horizontal is most efficient, they can effectively transport material at 30°, 45°, or even 90° (vertical), though capacity decreases as the angle increases.
Q: How do I clean the inside of the tube?
A: For food applications, we can design the unit with "easy-clean" features, such as drop-bottom cleanout doors or a reversible drive to empty the tube completely.
