Shaftless Screw Conveyor – Efficient & Non-Clogging Solution for Challenging Material Conveyance

Short Description:

The Shaftless Screw Conveyor is an innovative material transfer solution designed without a central shaft. Compared to traditional screw conveyors, its shaftless design uses a high-strength, flexible spiral that reduces clogging and enhances conveying efficiency—especially for sticky, entangled, or irregular materials.

Key Advantages

1. No central shaft: minimizes material blockage and entanglement
2. Flexible spiral: adapts to a variety of material types and installation angles
3. Fully enclosed structure: reduces odors and prevents environmental contamination
4. Easy maintenance and long service life

Applications

Shaftless screw conveyors are ideal for handling difficult or sticky materials that may cause clogging in traditional systems. Typical applications include:

✅ Wastewater treatment: sludge, screenings
✅ Food processing: leftover organic matter, fibrous waste
✅ Pulp & paper industry: pulp residue
✅ Municipal waste: hospital waste, compost, solid waste
✅ Industrial waste: metal shavings, plastic scraps, etc.

Working Principle & Structure

The system consists of a shaftless spiral screw rotating within a U-shaped trough, with an inlet hopper and an outlet spout. As the spiral rotates, it pushes materials from the inlet toward the discharge point. The enclosed trough ensures clean and efficient material handling while reducing wear and tear on the equipment.
