Stainless Steel Screw Conveyor for Straw Powder Solution

Product introduction of Stainless Steel Screw Conveyor

Stainless steel screw conveyor, also known as auger conveyor or spiral conveying system, is a high-efficiency bulk material handling solution used in industrial production lines.

It is designed to transport powder, granular, and biomass materials in a fully enclosed environment, preventing dust leakage and material contamination.

Compared with traditional conveying equipment, this screw conveyor solution offers higher automation level, lower maintenance cost, and better adaptability for complex industrial environments.

It is widely used in agriculture, food processing, chemical, and biomass industries.

Working principle

How does a stainless steel screw conveyor work?

Step 1. Material Feeding System
Bulk materials such as powder or straw are fed into the inlet hopper.

Step 2. Motor Driven Rotation
An electric motor drives the helical screw blade inside the tube.

Step 3. Continuous Material Pushing
The rotating screw pushes materials forward in a controlled movement.

Step 4. Enclosed Conveying Process
Material moves through sealed tube without dust leakage or contamination.

Step 5. Discharge Output System
Materials are discharged smoothly into the next production process stage.
