Industrial Shaftless Screw Conveyor Solution for Slurry

Shaftless Screw Conveyor Product Introduction

The industrial shaftless screw conveyor is a heavy-duty bulk material handling system developed for transporting powder, granule, paste, sludge, slurry, and semi-solid materials efficiently. Compared with traditional shafted conveyors, the shaftless spiral design minimizes material blockage and improves conveying performance for sticky, wet, fibrous, or irregular materials.

This conveyor system is suitable for horizontal, inclined, or customized conveying layouts in industrial production lines. The flexible spiral structure allows smooth transportation over different distances while maintaining stable material flow and reduced maintenance frequency.

Widely used in cement plants, wastewater treatment facilities, mining operations, food factories, plastic processing plants, and chemical industries, the shaftless spiral conveyor offers economical material handling performance with reliable long-term operation.

Working principle

Step 1: Material Feeding

Powder, sludge, slurry, or granular materials enter the conveyor inlet through a hopper or feeding system.

Step 2: Spiral Rotation

The shaftless spiral rotates at stable speed driven by the motor and gearbox assembly.

Step 3: Material Propulsion

The rotating spiral pushes materials forward continuously inside the conveyor tube.

Step 4: Continuous Conveying

Materials are transported horizontally or at inclined angles without interruption or material accumulation.

Step 5: Material Discharge

Bulk materials are discharged smoothly from the outlet into storage tanks, mixers, packaging systems, or downstream equipment.
