No matter how limited your site space may be, or how unique your materials are, we can provide a tailored solution specifically designed to meet your needs.

Technical Specifications

What Problems Can Our Shaftless Screw Conveyor Solve?

Problem 1: Material Clogging

Material entangles around the central shaft, leading to frequent shutdowns for cleaning and negatively impacting overall production efficiency.

Our Solution: By eliminating the central shaft, we structurally eradicate the possibility of entanglement.

Whether handling screenings from wastewater treatment plants or fruit and vegetable residues from food processing, materials flow through completely unimpeded.

Problem 2: Excessive Maintenance Costs

Traditional screw conveyors require frequent replacement of wear parts—such as bearings and bushings—making maintenance time-consuming, labor-intensive, and costly.

Our Solution: The shaftless design significantly reduces the number of critical wear parts. Routine maintenance requires only simple inspections, allowing for extended maintenance intervals.

Problem 3: Limited Installation Space

Limited floor space within a facility makes the installation and layout of traditional conveying equipment challenging.

Our Solution: Our Shaftless Screw Conveyor features a compact design that allows for both horizontal installation and inclined conveying at angles of up to 30°.

Problem 4: Dust or Liquid Leakage

Dust dispersion or liquid leakage during the conveying process compromises environmental hygiene and endangers worker health.

Our Solution: The conveyor trough is fully sealed along its entire length and utilizes high-quality sealing components to ensure that materials enter but do not escape. This makes it particularly suitable for industries with strict cleanliness requirements, such as food processing and pharmaceuticals.

Problem 5: Customization Challenges

Materials possess unique characteristics (e.g., high temperature, high corrosiveness), or the equipment requires automated integration with existing production lines.

Our Solution: We offer comprehensive customization—ranging from materials and structural design to control systems—to ensure the equipment integrates seamlessly into your specific production workflow.

Which Industries Can Benefit from Shaftless Screw Conveyors?

Environmental & Water Treatment: Conveyance of municipal and industrial sludge, screenings, and dewatered filter cake.

Food Processing: Hygienic conveyance of materials such as fruit peels and residues, spent grains, dough, and slaughterhouse by-products.

Agricultural Biomass: Processing of organic waste, including chopped crop stalks and livestock manure.

Mining & Metallurgy: Reliable conveyance of abrasive materials such as slag, tailings, and pulverized coal.

Pulp & Chemical: Handling of specialized materials, including viscous pulp, coatings, and resins.

FAQ

Q: Should I choose a shaftless or a shafted screw conveyor?

A: This depends on your specific material.

If your material is loose, dry, and non-sticky, a shafted conveyor is the most economical choice.

However, if you are handling sludge, food waste, fibrous materials, or substances prone to tangling or clumping, a shaftless conveyor is the only option that ensures stable, long-term operation and prevents clogging.

Q: What is the maximum conveying distance for the equipment?

A: A standard single-section unit can convey materials up to 15 meters. For longer distances, we utilize a proven multi-section drive splicing technology; we have successfully implemented long-distance conveying projects exceeding 48 meters, demonstrating stable and reliable performance.

Q: Will highly viscous materials stick to the screw flights during conveying?

A: We possess extensive experience in handling highly viscous materials. By employing a combination of techniques—including optimizing flight pitch, applying surface polishing treatments, and selecting low-friction liners—we can effectively minimize material adhesion and ensure clean discharge.

Q: Will I need to frequently replace parts during long-term operation?

A: The primary maintenance points involve the seals and wear-resistant liners. Under normal operating conditions, high-quality seals typically last 6 to 12 months, while the wear-resistant liners can last anywhere from 1 to 3 years.

Replacement procedures are simple and quick, and we provide clear instructions to guide you through the process.
